Upper Darby Police Superintendent Michael Chitwood says 36-year-old George Rogers tried to stab officer Dan Lanni early Sunday morning. Rogers is charged with attempted murder, aggravated assault, terroristic threats and other charges.
Chitwood says officers were responding to a call from a man who said he had a crossbow and would burn down his house when they found Rogers barricaded in a bedroom.
Chitwood says Rogers tried to stab Lanni with a 13-inch sword but the officer was protected by a Kevlar shield. Another officer subdued Rogers with a stun gun.
Authorities say crossbows and other weapons were found in the room.
Rogers is being held on $75,000 bail.
