Knife amnesty begins in police stations across Plymouth
A month-long knife amnesty has started in Plymouth.
Secure bins have been placed in the city's police stations for people to dispose of knives without facing prosecution.
Anyone wanting to take knives to police stations is asked to wrap them up securely before leaving the house.
Supt Andy Boulting said: "If they are not needed or wanted we would ask people to hand them in to their local station."
"We believe there may be a considerable number of knives held in homes, outbuildings and business premises.
"They may have been overlooked, forgotten or people simply don't know how to safely dispose of them," he added.
Victim Support said that a knife attack could have a big emotional and financial impact on the victim beyond the injury itself, with people having to take time off work.
In previous amnesties more than 600 weapons were handed in across the city.
