Police have arrested four people as part of an investigation into motorbike thefts in York.
Operation Ignition is the operation to tackle the crime.
Last week officers arrested two men, both aged 20, and two boys, aged 17 and 15, on suspicion of a number of motorcycle thefts between September and November 2024 in the York area.
All four were questioned and have been released on conditional bail while enquiries continue.
PC Ben Ambler, lead officer for Operation Ignition said: “Despite some positive results and reductions in reports of thefts towards the end of the summer, the last few months saw a spike in motorcycle thefts across the city.
“Our officers have used a range of tactics, including specialist resources, drones and plain-clothes officers to disrupt groups of motorcycle thieves – leading to a 70% reduction in thefts so far in December.
“We are committed to tackling this issue and will continue to disrupt and apprehend those responsible for this type of crime.”
Police advise owners to keep their motorbikes out of sight and to “layer your security”.
“These types of thefts tend to occur between late evening and the early hours, with offenders targeting vehicles parked on the street, on driveways or in gardens and attacking the security of the vehicles. Offenders will typically arrive on the scene on bicycles.
“Please continue to be vigilant and report anything suspicious to the police on 101, or 999 if a crime is in progress.”
