MARION CENTER, Pa. (AP) - State police are investigating after a 16-year-old western Pennsylvania girl who reported finding a razor blade in her Halloween candy was treated for cuts in her mouth.

Troopers from the Indiana, Pennsylvania, barracks say the girl was treated Monday.

Trooper Mark McMahan said Tuesday the girl reported receiving the razor in a piece of bubble gum she received during a community event in the Marion Center area. That's about 60 miles northeast of Pittsburgh.

The event involved 22 people who registered to hand out Halloween treats out of their vehicles at a school parking lot in East Mahoning Township.

More than 300 children received treats, and nobody else reported that anything was tainted.

No suspects had been identified and no charges have been filed.
