Reigate police station is one of 25 across the county taking part in a national knife amnesty.

People have until June 30 to dump their knives in a secure red wheelie bin at the front counter without the fear of being prosecuted.

Chief Inspector Stuart Sang, who is coordinating the amnesty in Surrey, said: "People wrongly think they're protecting themselves by carrying a knife all they're actually doing is risking a four-year prison sentence."

He added: "I would urge anyone who carries a knife to take this opportunity and hand it to us during the amnesty or risk enforcement action.

"Every knife handed in is a potential weapon that can't be used in a crime."

A joint billboard campaign by the Home Office and the Association of Chief Police Officers is warning people about the dangers of carrying knives and encouraging them to dispose of blades at their local police station. It is the first national knife amnesty in 10 years.

At Reigate police station in Reigate Road people can drop knives into the bins Monday to Sunday from 7am-10pm.
