Oak Lawn police are looking for a resident who stabbed another resident Monday night after a confrontation in an alley near 97th Street and Ridgeland Avenue, police said.

The 35-year-old victim was riding his bicycle through the alley about 10 p.m. when he exchanged words with a boy younger than 14 who was setting off fireworks, police said.

They said the boy’s father confronted the victim and stabbed him in the stomach with a knife before fleeing.

The victim went to a nearby house for assistance and was taken to Christ Medical Center, where he was treated and released a few hours later, according to police.

They said the two men had no prior relationship.
