CHRISTMAS, Fla. -- November 25, 2012

The Orange County sheriff's bomb squad blew up two old hand grenades found in a field.

Deputies say children playing in a field in the rural town of Christmas found the first grenade Saturday afternoon. One of the children told a parent, who called deputies.

The grenade appeared to be at least 30 years old. The bomb squad blew it up and then found the second. They detonated it, too.

Deputies plan to inform the Army Corps of Engineers to find out whether the field was once used for military training and might have other grenades. Deputies said it is also possible someone buried the grenades there years ago to dispose of them.
