Chicago police are searching for seven people wanted in connection with a robbery on a CTA Red Line train last month in the Greater Grand Crossing neighborhood.

Around 12:35 a.m. on March 22, a group of people approached a Red Line passenger on a northbound train near the 79th Street stop, attacked him, cut his hand, and stole his belongings, according to police.

Police released a community alert on Tuesday showing surveillance images of the seven suspects, and asked anyone with information to contact public transportation detectives at 312-745-4447.
