Witnesses chase down Chicago robber

CHICAGO (AP) — A man who allegedly tried to steal the purse of a woman amid the horde of Chicago Black Friday shoppers was thwarted by a couple of Good Samaritans.

Police say they might not have caught the bad guy without the civilian help.

Chris Frieden of Indianapolis, in Chicago with his family, said he was in his car when he heard a shriek and saw a man choking a woman and grabbing her purse. He, along with nearby resident Mike Hochhauser, gave chase as the alleged attacker tried to flee.

The men tracked the suspect to high-end Michigan Ave., where he hailed a cab. Frieden and Hochhauser stopped the cab and trapped the suspect inside until police arrived.

Police say 31-year-old Richard Mendoza is charged with strong armed robbery and battery.
