Police substation shut down after woman brings in grenades

Officials say a South Florida police substation was shut down for several hours after a woman brought in two grenades she found in her home.

Local media outlets report that the woman brought the devices to the Miami-Dade Police Department's West District Station on Tuesday afternoon. She said she found them while cleaning.

The bomb squad responded and immediately evacuated the building. Officers detonated the grenades in a nearby field. It wasn't known if they were live.

Police say they don't plan to charge the woman who brought in the grenades. Officials say anyone who finds a possible explosive device should call 911 rather than move it to a police station or other location.
