Dunedin man Dennis Hodge did not expect the Countdown Central car park near the Dunedin central police station to be evacuated when he brought in an old practice mortar bomb yesterday.
Police cars with flashing lights sealed off all four entrances and exits to the supermarket car park, and also sealed off a nearby block of Great King St, after police were alerted about 9.35am.
Senior Sgt Mark Gill said that after Mr Hodge went into the police station and advised that mortar bomb - apparently an inactive training round - was in his car, parked nearby in the car park, police staged the precautionary evacuation, to ensure public safety, reports Otago Daily Times.
People were allowed to drive away cars already parked in the car park, but no shoppers were allowed to drive in, and pedestrians could not walk through the central car park area.
Snr Sgt Gill said the Ministry of Defence bomb squad quickly confirmed that the mortar bomb was safe and did not contain explosives, and the cordon was lifted, about 10am.
