A woman raking her yard discovered a military training grenade in a pile of leaves, forcing the evacuation of several neighboring homes while a bomb squad removed the device.

It wasn't clear if the grenade was live or how it ended up in the home's backyard, where the woman found it Wednesday morning.

"The lady was, of course, upset. She just moved into the house," said Orlando Fire Department Deputy Chief Kathy Miller. "Arson units checked the backyard to make sure there were no other devices and they didn't find anything."

The arson bomb squad turned the grenade over to the U.S. Army.
