Chicago police are asking for help identifying three people wanted in connection with an armed robbery last week on a Green Line train on the South Side.
The trio approached a 31-year-old man about 5 a.m. March 2 on a train near the 35th-Bronzeville-IIT station, Chicago police said.
They allegedly threatened the man with a knife and took his property, police said.
Anyone with information was asked to call detectives at 312-745-4443.
