BOMB disposal experts were called to a council depot after a live grenade was discovered.
Police and the Royal Navy bomb disposal team attended Havant Borough Council’s Penner Road depot, where refuse trucks are kept, just after 7.30am today.
A smoke grenade - which is used for training and does not explode - was found close to recycling bins.
It was made safe and removed by 10.15am.
A Hampshire Police spokesman said: ‘A cordon was put in place and an evacuation of the immediate area around Penner Road to Southmoor Road was undertaken while the device was assessed.
‘The device was removed and a controlled explosion has been undertaken, the cordon has now been lifted.
‘This is being treated as an isolated incident and there is no threat to the public.’
Jackie Batchelor, the council’s head of environment, said: ‘We would like to thank Hampshire Constabulary, the bomb disposal team and our staff for their prompt response to this incident.’
