Police were called to a Cirencester estate at the weekend after children found a suspected hand grenade.
The Corinium Via estate was cordoned off on Saturday afternoon after a bomb disposal team attended the scene.
It came after two boys discovered what is believed to have been a grenade within some tree roots near Parry Close, a road off Forstall Way.
Cars were briefly prevented from accessing the estate while police made the area safe.
Mayor of Cirencester Claire Bloomer said in a Facebook post on Saturday evening: “The device has been safely disposed of.
“Many thanks to our local police officers and the bomb disposal team.
“The estate is now safe and residents are free to return.”
