TINLEY PARK, Ill. (STMW) — Five men were in custody Saturday night after they allegedly entered a restaurant and began beating patrons gathered for a wedding with bats in southwest suburban Tinley Park.

The attack occurred at the Ashford House Restaurant at 7959 159th St., said Tinley Park Fire Chief Ken Dunn.

The emergency call said a group of 15 people dressed all in black entered the restaurant at approximately 12:45 p.m., according to a police release. They were targeting a specific group of people eating in the restaurant.

The group fled the scene in three vehicles, one of which was apprehended five minutes later at the intersection of 159th Street and Harlem Avenue. The other vehicles escaped, according to the release.

Ten people were injured in the attack, and three were taken to local hospitals, according to the police release. The rest of the injured declined treatment.

The attack is under investigation by the Tinley Park Police Department and the South Suburban Major Crimes Task Force. Police believe the incident is isolated and not random.

Tinley Park Mayor Edward Zabrocki declined to comment on the investigation.
