VIENNA (AP) — One Austrian police station has dodged an explosive situation.

The police station in Eisenstadt, east of Vienna, was evacuated Tuesday after a woman walked in with a live tank shell in her hand.

A police statement Wednesday says the shell was exploded without incident after experts transported it to a nearby sandpit. But they have issued a warning to all not to touch or pick up anything that could be ordnance left over from World War II.

The statement says the woman who brought in the shell told police her son had found it over six months ago — and they had been storing it in their garage ever since.
