York’s police HQ was evacuated this morning (Wednesday).
Officers and civilian staff had to leave Fulford Road Police Station at about 10.15am after someone handed in a grenade.
They called in the bomb squad to check out the Second World War-era hand grenade.
A North Yorkshire Police spokesperson said: “The Army Explosive Ordnance Disposal team confirmed the device is safe and they attended to remove the grenade.
“The safety cordon at police station was immediately reduced with officers and staff being allowed back in the building before 10.30am.
“There has been no disruption to the Force Control Room or the security operation in place for the Royal Visit in York.”
