mugging in alley between S St NW & Randolph Pl NW: gun used

See this message from a Randolph Place NW resident:

Just wanted to let you know and have you spread the word of a mugging of a Bloomingdale resident, that took place in Bloomingdale.

I had a brief chat with him, and below is a recap of your conversation:

He said that it all happened very quickly and left him in a dazed state.

He was coming home on Sunday morning between 12:00am - 12:30am. He entered the alley way from 1st Street, via S street and when he was about to turn left to go up the alley, two guys who were waiting to ambush a passer-by jumped him.

They put a gun to his chest and robbed him of his wallet and cell phone.

They were completely covered from head to toe and he cannot identify them.

They didn`t physically harm him. He called the cops and filed a report.

He`s physically ok but was in a state of shock and is slowly recovering from the incident.
