Chicago police released surveillance photos of a group of teenagers who attacked three people at the Chicago Red Line station on Saturday evening.

At 7:12 p.m., the teens approached the victims on the station’s platform before surrounding them an punches were thrown, according to Chicago police.

The unprovoked attacks targeted a 26-year-old man, a 28-year-old man and a 29-year-old woman, according to police and the victims, who were all treated at the scene for bruising and lacerations. According to the 28-year-old, he later learned learned that he had suffered a broken eye socket when he received additional treatment at University of Illinois Medical Center at Chicago.

“Because they hit random people for no reason and I live very close to the station, I am worried to live here anymore,” he told the Sun-Times.

Police also received reports that a large group of teens had been kicked out of Water Tower Place and a nearby McDonald’s on Saturday night.

Downtown CTA stops had an increased police presence in the lead-up to the New Year’s Eve festivities, and officers were made “highly visible” at the Chicago station in the wake of the brazen attacks, police said.
