PITTSBURGH Authorities say a confrontation stemming from an earlier altercation led a man to stab three people inside a Target store in Pittsburgh, including a 16-year-old girl who was seriously injured.

Police say a man brandishing a knife ran into the store in Pittsburgh's East Liberty section shortly after 5:30 p.m. Monday and was pursued by two other men.

A police spokeswoman says the knife-wielding man grabbed a teenage girl standing with family members inside the store and ended up stabbing her and slashing two men. She was listed in serious condition at Children's Hospital.

The injured men were taken to UPMC Presbyterian Hospital, and a bystander was taken to UPMC Shadyside Hospital for chest pains. A police officer was treated for exposure to pepper spray.

A suspect was arrested.
