Some 100 weapons have been retained by Lincolnshire Police, with one day to go of their firearms amnesty.
The call to weapons to be brought in to Lincoln, Grantham, Boston or Skegness stations was launched on November 3. It ends on Friday, November 14.
Anyone handing in a weapon can ask to remain anonymous, however should officers discover that the firearm has been used in an incident they may wish to contact that person again for help with investigations.
At 5pm on Wednesday, November 12, a total of 100 firearms had been handed in.
Of the 100 weapons handed into the force since the beginning of the amnesty, were 13 revolver pistols and handguns, 10 rifles, 39 shotguns, 17 imitation weapons, 20 air weapons and one stun gun.
A small amount of ammunition has also been handed in, but has not been counted by police currently.
Officers are urging anyone who has been thinking about handing in a weapon to do so tomorrow in a final push for the amnesty period.
