WILKINSBURG, Pa. (AP) - Authorities in western Pennsylvania say a K-9 officer was stabbed to death and a suspect shot during a foot pursuit on a transit busway.

Spokesman Jim Ritchie of the Port Authority of Allegheny County said the pursuit began Sunday afternoon at a transit station in Wilkinsburg just outside the city of Pittsburgh.

He said authority and police officers chased the suspect along the transit busway that leads from downtown Pittsburgh into the city's eastern suburbs.

Ritchie said that during the pursuit, the suspect stabbed the Port Authority K-9 officer and the animal died. He said police officers shot the suspect.

Ritchie said the suspect's condition wasn't immediately available and he didn't know what prompted the pursuit.
