A man was robbed of his iPhone and wallet while waiting for a CTA train Wednesday night, police said.
Three to five men approached the 20-year-old victim around 10:45 p.m. at the Harrison Red Line "L" platform and attacked him, hitting him in the face and knocking him to the ground. They stole his phone and money, police said.
But the thieves didn't get very far.
Minutes later, members of the Guardian Angels spotted a group of men running near the Roosevelt station. The Angels followed the men, and when police officers asked if they'd seen anyone matching the description of the robbers, they knew where the group was located.
The men were arrested shortly after and were being questioned Thursday morning.
"It's a good feeling, but at the same time we're just a visible crime deterrent," said Miguel Fuentes of the Guardian Angels. "We do this all the time. Six days a week we patrol the CTA trains, subways and platforms, and we just want to be out there and help the police department in any way possible."
The Guardian Angels were focused on the Roosevelt station after a 21-year-old was shot there Monday night after a reported argument.
