Police are warning residents of two armed robberies last month in the Logan Square neighborhood on the Northwest Side.

In two incidents on Dec. 19, a male got out of a white four-door vehicle and walked up to the victims, announcing a robbery and demanding their property while armed with a handgun, Chicago police said.

The robberies occurred about 4:10 a.m. in the 3800 block of West Fullerton Avenue and at 2:01 a.m. in the 3900 block of West Fullerton Avenue, police said.

The robber fled in a white vehicle after both incidents, police said. It was not clear what was stolen from the victims.

Anyone with information was asked to contact Area North detectives (312) 744-8263.
