Cyclists in Southampton are being urged to buy locks, after a surge of bike thefts.
There were 54 bike thefts between September and October, according to police.
Hampshire police will be selling locks at discounted prices later this week.
Sgt Jeanette Maidment, said in a statement: “It can be incredibly upsetting, not to mention frustrating, when someone has their bike stolen.
“For many people, a bike is their main mode of transport and used as part of everyday life.
“We want Southampton’s residents to feel they are able to ride their bike without the fear of being stolen.”
Police will be selling the locks in Marlands Shopping Centre, Southampton, this Thursday from noon.
More officers will also be patrolling areas in Southampton in a bid to reduce bicycle thefts.
Sgt Jeanette Maidment added: “Operation D-Lock is a neighbourhood initiative that promotes bike security and focuses on enhancing our chances at capturing quality evidence, such as CCTV, and link reports where possible, to identify offenders.”
D-Locks are being recommended by police over cable locks, which can be easily cut through. They usually retail from around £30.
