A bomb squad was sent to a beach in Yorkshire after a boy found a hoard of wartime bullets.
The child is believed to have pocketed the bullets and the alarm was raised after they were discovered by adults.
A bomb disposal team was then sent to Skirlington beach make the area safe.
It is not clear whether the child took the bullets home or whether he was discovered with them whilst still near the beach, which is near a former RAF bombing range.
The Bridlington, Driffield and Hornsea community policing team wrote on its Facebook page on Saturday: "Hornsea PCSOs are currently dealing with some unexploded ordinance at Skirlington after a child was found to have collected items from the beach.
"Please do not remove any item from the beach you know or suspect to be ammunition or a bomb.
"You have no way of telling if they are still dangerous and even training rounds can still carry a charge that can cause substantial injury.
"Items often wash up and become exposed on our coast due to the now disused RAF Cowden bombing range south of Mappleton.
"If you find any item of unexploded ordinance on the beach or coastal areas then please call 999 and ask for the Coastguard or the police."
Anyone who comes across similar explosives is being urged to treat them as dangerous and stay away from them, and to call 999 immediately and ask to speak to the police or the coastguard.
