Police were alerted after a boy found a gun on a beach in Co Down at the weekend.
The weapon, believed to be a revolver, was found at the St John’s Point area of Killough on shortly before 8pm on Sunday evening.
A PSNI spokesperson said: “The weapon, which was in a very poor condition, has been removed for examination.”
It comes just days after a boy found a gun in Lisburn. The discovery was made around 6.30pm last Thursday in Gregg Street, which is just a short walk from the headquarters of Lisburn and Castlereagh City Council
