TURBOTVILLE, Penn. --  A 76-year-old U.S. man is in jail after police say he went after his housemate with a chain saw.

Guy Allen Black is being held on $100,000 bail after allegedly cutting through a door at the home he shared with Ronald Lee Tanner and swinging the chain saw at him.

Pennsylvania state police say Black became angry after Tanner changed the locks on the home.

Investigators say the chain saw got stuck on Tanner's shirt and jammed, allowing Tanner to pin Black down with an umbrella.

Tanner was unhurt. It's not immediately clear if Black has an attorney.
