KEW GARDENS, Queens — The NYPD has released surveillance footage of the person they believe attacked and raped a woman in Queens Monday morning.

Video shows a man looking around near the scene of the attack minutes before the attack occurred. Police have not been able to identify him, but they consider him a person of interest in what they are treating as a sexual assault case of a woman.

The woman, 52, was found unconscious at the bottom of an exterior stairwell in the area with her pants pulled down in the vicinity of 72nd Road and Kissena Boulevard, bordering Pomonok and Kew Gardens Hills, police said.

She had trauma to her face and body, and was hospitalized in critical condition. Officials said the woman had just dropped her off son to school before she was attacked.

Authorities said the woman did not know the attacker and that the incident was a "violent, random attack."

Police are offering a $10,000 reward for information leading to an arrest.
