Three youths followed a Red Line commuter and robbed him Monday night in the South Loop, police said.

About 8 p.m., officers were called to Cullerton Street and Wabash Avenue after the victim told police three suspects followed him after he’d gotten off a Red Line traian and then robbed him of his cell phone, his wallet and backpack, according to police.

After the robbery, the suspects fled west on Cullerton, police said.

The age of the victim was not immediately known.
