A crazed man allegedly stabbed a woman in the neck with a shard of glass while she was walking around SoHo, a ritzy shopping area in Manhattan, on Monday afternoon.

The victim was a 25-year-old woman, and police have detained a person of interest, a New York City Police Department (NYPD) spokesperson told Fox News Digital. 

Police did not share any further information about the person of interest.

Around 3 p.m., a 911 caller reported an assault in progress.

“From what I heard, a lady was about to get robbed for her bag… He went to the other lady, cut and robbed her back and cut her in the neck with a piece of glass and then ran up the block,” a bystander in the area named Jordan P. said.

The bystander further described the victim as “really pale.” He also said he heard a woman screaming for help.
