A box containing an old train set - and what was believed to be a corroded mortar bomb - triggered a major police callout in central Dunedin.
The drama ended when the ordnance - later identified as a smoke bomb from the 1970s - was removed and detonated at a safe place by the Burnham-based New Zealand Defence Force bomb disposal unit.
Dunedin Hospice Shop manager Cat Callanan was sorting through recycled metal when she came across a ''lovely old train set'' in a box yesterday.
She also found a corroded item, shaped like a bomb, which she picked up to show another staff member.
