Assistant Chief Constable Darren O'Callaghan has officially assumed the role of Head of Crime and Criminal Justice at Thames Valley Police.
The appointment, effective today, Monday 3 August 2026, places the seasoned officer at the helm of one of the most extensive policing portfolios in the United Kingdom.
Thames Valley Police, the territorial police force responsible for the counties of Buckinghamshire, Oxfordshire, and Berkshire, confirmed that O'Callaghan took up the post this morning.
He brings with him decades of experience, having transferred to the force in April 2026 from the Hampshire & Isle of Wight Constabulary.
His arrival comes at a critical juncture for the force, which is currently grappling with evolving technological challenges and significant pressures within the wider criminal justice system.
O'Callaghan steps into the position vacated by his predecessor, tasked with overseeing the strategic direction of crime management, criminal justice processes, and operational policing across the region.
In a statement released this morning, O'Callaghan expressed his enthusiasm for the new challenge.
He emphasised his commitment to building on the improvements already made within the force and driving forward initiatives to protect communities across the three counties.
The role is not merely administrative; it requires direct command over serious crime investigations, intelligence-led policing operations, and the management of the force's interaction with the Crown Prosecution Service and the courts.
Officers within the force hierarchy have described the position as pivotal for maintaining public confidence and ensuring that the complex machinery of criminal justice functions efficiently across the Thames Valley area.
The force serves a population of over 2.3 million people, covering a diverse geographic area that includes the urban centres of Milton Keynes, Reading, and Oxford, as well as extensive rural communities.
Managing crime across such a varied landscape requires a nuanced approach, balancing the needs of densely populated towns with the specific vulnerabilities of rural locations.
O'Callaghan's extensive background in intelligence and tasking is expected to play a significant role in refining how the force allocates its resources to these differing areas.
Officials said the appointment process was rigorous, focusing on candidates with proven track records in complex crime management and strategic leadership.
His selection signals a continued focus by the Chief Constable on bolstering the force's senior ranks with officers possessing diverse experiences from other UK forces.
The move is part of a broader strategy to ensure Thames Valley Police remains resilient against national trends in offending while addressing localised concerns.
O'Callaghan's immediate priorities will likely involve assessing the current performance of the crime and criminal justice directorate and liaising with key stakeholders in the region.
This includes the Police and Crime Commissioner, local councils, and community safety partnerships, all of whom have a vested interest in the new Head of Crime's strategic vision.
The force has faced scrutiny in recent years over its handling of certain crime categories, making this appointment a matter of significant public interest.
However, recent performance indicators suggest a stabilisation in key areas, a trend O'Callaghan will be expected to maintain and improve upon.
His tenure begins at a time when policing is increasingly in the national spotlight, requiring a leader capable of navigating both political pressures and operational realities.
The announcement has been met with cautious optimism by staff within the force, many of whom are looking for clear direction amidst a period of substantial change.
As he settles into his office at the force headquarters, the sheer scale of the responsibility awaiting him is undeniable.
The Thames Valley area presents unique policing challenges, from the high-tech crimes associated with its academic and technological hubs to the traditional rural crimes affecting its farming communities.
O'Callaghan's experience in Hampshire, a force with a similar mix of urban and rural responsibilities, is viewed as a strong asset in this regard.
His previous role involved a focus on development and intelligence, areas that are becoming increasingly critical in modern policing.
The ability to predict crime hotspots rather than simply reacting to them is a core tenet of contemporary police strategy, and O'Callaghan is known to be a strong proponent of this proactive approach.
Sources within the force suggested that his first week will involve a series of briefings with department heads and a review of ongoing major investigations.
This is standard procedure for senior officers assuming command, ensuring a seamless transition in leadership and continuity in critical operations.
The force has been without a permanent Head of Crime and Criminal Justice for several months, making today's appointment a crucial step in restoring stability to the senior command team.
The temporary arrangements put in place during the interim period will now be dismantled as O'Callaghan asserts his authority over the directorate.
His leadership style, described by former colleagues as collaborative yet decisive, will be tested almost immediately as he confronts the pressing issues facing the force.
Among the most pressing of these issues is the rise in the use of powered transport for criminal activities, a problem that has plagued forces across the Home Counties.
Thames Valley Police has been at the forefront of attempts to curb this trend, deploying new technologies and tactics to disrupt offenders who rely on e-scooters and e-bikes to evade capture.
This specific challenge will demand a significant portion of O'Callaghan's attention in the coming months.
The force covers a vast area, and the mobility afforded to offenders by these vehicles has made traditional policing methods less effective.
Consequently, the strategy to combat this issue requires innovation and a willingness to embrace new tools, an area where the new ACC is expected to make his mark quickly.
Force Deploys SmartTag Spray Against Rising E-Scooter Threat
Thames Valley Police has escalated its war against illegal e-scooters and e-bikes with the deployment of SmartTag spray technology.
This tactical shift comes amid a surge in complaints from residents across Buckinghamshire, Oxfordshire, and Berkshire regarding the anti-social use and criminal utilisation of powered two-wheelers.
The force has already seized more than 100 illegal machines in recent months, a statistic that underscores the scale of the issue facing the new Head of Crime.
The SmartTag system allows officers to tag offenders with a unique, invisible DNA code that remains on their skin and clothing for weeks.
This forensic link provides irrefutable evidence connecting an individual to a specific crime or incident, effectively removing the need for dangerous high-speed pursuits through crowded streets.
Officials said the technology has been a game-changer in identifying suspects who would otherwise disappear into the urban landscape.
The move follows successful trials by Dorset Police and other southern forces, which have reported significant reductions in nuisance riding and related thefts since adopting the spray.
A BBC report in April highlighted Thames Valley Police's decision to integrate SmartTag into its standard response protocols, marking a significant investment in forensic technology.
The problem is not merely one of nuisance; these vehicles are increasingly used for snatch thefts, drug dealing, and as getaway vehicles for more serious offences.
Their agility allows riders to evade police cars and even helicopters in some terrains, necessitating a different approach to apprehension.
By using the spray, officers can target the rider rather than the vehicle, ensuring that even if the bike is abandoned, the offender can be traced and prosecuted later.
This tactic is part of a broader strategy announced by the force to tackle the growing menace of unpowered and powered transport crime.
The force covers Oxfordshire, Buckinghamshire, and Berkshire, areas where the use of these vehicles has become particularly problematic in town centres and residential estates.
In Milton Keynes, the extensive redway system has been exploited by riders, while in Reading and Oxford, historic narrow streets have become hotspots for anti-social behaviour.
The seizure of over 100 machines represents a tangible success, but officials acknowledge that it is only the tip of the iceberg.
Many more are believed to be in operation, flown under the radar of traditional enforcement.
The legal framework surrounding e-scooters remains complex, contributing to the enforcement challenges.
While rental schemes exist in some areas, private use on public land remains largely illegal, creating confusion among the public and difficulties for officers on the ground.
O'Callaghan's remit will include navigating these legal complexities while ensuring his officers have the clarity and tools they need to enforce the law effectively.
The deployment of SmartTag spray is a clear indication that the force is prioritising evidence-based interventions over physical confrontation.
Chasing e-scooters poses significant risks to the rider, the public, and the police, a risk that the force is keen to minimise.
The spray allows for a more measured, intelligence-led approach to enforcement.
Once an offender is tagged, they can be arrested at a later time and at a location of the police's choosing, significantly reducing the likelihood of a violent confrontation.
This method has been praised by road safety groups, who have long campaigned for safer alternatives to pursuits.
However, the effectiveness of the strategy relies heavily on public awareness.
The deterrent effect only works if potential offenders know that the spray is being used and that it will lead to their arrest.
The force has launched a local publicity campaign to highlight the use of SmartTag, warning riders that they are being watched.
Community engagement officers have been visiting schools and youth groups to explain the dangers and legal consequences of illegal e-scooter use.
This preventative work is just as important
