A gun and knife amnesty is due to start to help tackle gang-related crime and disorder in Derby.
The four-week long amnesty will run from 15 June until 12 July, Derbyshire Police said.
It is the first time a gun amnesty has taken place in the city. Weapons can be handed into local police stations throughout the city.
Derbyshire Police and Derby Community Safety Partnership have joined forces for the initiative.
Ch Supt Andy Hough said: "We have successfully held knife amnesties in the past and this has been extended this time to include guns as part of our overall work in the city.
"Police intelligence locally and nationally shows that the vast majority of gun-related crime involves weapons that are mainly old or even antique.
"It is therefore timely that we hold the gun amnesty in the city to give people who have guns in their homes - perhaps that they have found or inherited, however old - the chance to be able to hand them in and reduce the risk of them falling into the wrong hands."
Sharon Squires from Derby Community Partnership said: "Every gun and knife that is handed into the police is one less that can be potentially used on the streets of Derby.
"The prevalence and serious nature of criminal activity of gangs is certainly nowhere near as serious in Derby as in other cities around the UK, but that does not meant that we can sit back on our laurels."
