VIDEO: Chicago woman fends off alleged knife-wielding robber

CHICAGO -- Surveillance cameras caught the moment a man allegedly armed with a knife ran into a Chicago garage and tried to rob a woman, reports CBS Chicago.

The daylight robbery occurred Saturday in the city's trendy Bucktown neighborhood. Surveillance video shows a gray car driving past an open garage just after a woman went inside it. The car stops suddenly, and a man carrying what appears to be a weapon gets out and enters the garage.

The victim, a nanny for a family who lives in the home attached to the garage, said the assailant had a kitchen knife. But the nanny fought back, according to Steve Jensen, president of the Bucktown Community Organization.

"It appears she struggled and hollered and screamed, yelled and the guy fled without taking anything," Jensen said.

Jensen said that despite a proliferation of security cameras in the neighborhoods, stickups are not uncommon.

"Every couple of weeks there's an event just like this, whether it's someone on the street being accosted or somebody in their yard or garage," Jensen said.
