Police are searching for a suspect after a 90-year-old woman was attacked while walking along a Brooklyn sidewalk earlier this week, and surveillance video obtained by a local news station appears to capture the violent encounter.

The assault happened around 9:47 a.m. Monday outside 501 Brighton Beach Ave. in the Brighton Beach neighborhood, according to the New York City Police Department (NYPD).

Surveillance video obtained by News 12 appears to show the suspect pushing what looks like a discarded baby crib filled with debris along the sidewalk before suddenly lifting it and throwing it at the elderly woman as she walks past. The impact knocks the woman to the pavement as the suspect appears to calmly continue walking away.

Emergency medical personnel responded and transported the woman to NYC Health + Hospitals/Coney Island, where she was listed in stable condition, police said.

Police have not identified a motive for the attack, and it was not immediately clear whether the suspect and victim knew each other.

The suspect remains at large.

The NYPD released a photo of the man investigators are seeking. He is described as wearing a dark-colored hooded sweatshirt, black pants and white sneakers at the time of the attack.

Anyone with information about the suspect's identity or whereabouts is asked to contact the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477). Tips can also be submitted online through the Crime Stoppers website or by messaging @NYPDTips on X. Police said all calls and tips will be kept confidential.
