A man tried to talk to a woman inside a Queens building lobby, then slashed her neck when she ignored him, according to police, who are now looking for the suspect.

The man, believed to be about 20 years old, approached the 26-year-old victim in the lobby of a Jamaica building after 5 a.m. on Oct. 1, police said.

He tried talking to the woman and when she turned away, he grabbed her from behind and used some sort of cutting instrument to slash her neck, according to police.

The victim was taken to the hospital, where she was listed in critical but stable condition. An aquaintance of the victim told NBC 4 New York that she is recovering, but that she suffered damage to her vocal chords.

The attack has neighborhood residents on edge.

"I'm worried now for my daughter and my wife," said Hans Persaud.

Anyone with information is asked to contact Crime Stoppers at 800-577-TIPS.
