Bike thieves are being warned it will be easier for police to catch them red handed thanks to a free service being offered in Aylesbury Vale.
A bike marking session is being held at Halfords in Broadfields, with unremovable security marks showing who owns the bike and acting as a deterrent to thieves as it can be easily checked by police.
If a bike is stolen and then recovered, police can trace the owner and make sure it is returned to them.
It also means they can prosecute the person they catch riding the bike for theft or handling stolen goods.
New bikes bought at Halfords are free for marking as well as those that are old and brought along for the September 7 event.
The event has been organised by Aylesbury Vale District Council and Thames Valley Police.
Councillor Pam Pearce, cabinet member for community matters, said: “Bikes are often very valuable possessions and it can be very upsetting when they are stolen.
“It is vital to secure any bike which is going to be left unattended, even if the owner is only going to leave it for a short period of time.
“We are working very closely with the police to remind people to lock up their bikes so we can work together to reduce the number of incidents in Aylesbury Vale.”
