A woman who made an innocent discovery with her newly purchased metal detector ended up prompting the evacuation of her local police station.
ABC News Australia reports that Fairlie Pirouc was testing out the detector on a beach in the southeastern state of Victoria when she dug up what she initially identified as "a bomb" and then "perhaps a shot put."
Pirouc and her husband took it home, then to a nearby military base, where they were advised to turn it in at the police station.
"They took one look at it and said, 'Ahh yes, I think we better keep that one,' so they went down into lockdown and called in the bomb disposal unit," Pirouc's husband Pete told ABC News.
The station was evacuated while the device was removed from the station.
It turned out to be a more than 120-year-old cannonball, likely fired from a navy ship during a training exercise in the 19th century.
Now, not all things found by metal detectors cause havoc; some bring joy.
Back in July, a Boca Raton woman received her husband's wedding ring in the mail after it had been found by a man with a metal detector on a beach in Los Angeles.
