A 73-year-old woman was shoved onto the subway track in Brooklyn during an altercation on Monday.

The incident happened at the Clinton-Washington Avenue subway station at around 1:30 p.m. when a fight broke out between the elderly woman’s husband, 82, grandson, 30, and the suspect whose image was released by police but not yet identified, according to FOX5.

The incident reportedly began after the grandson asked the suspect who approached them to stop smoking on the subway platform. The request led to an argument and then a physical altercation when the suspect punched and kicked the grandson in the face.

The grandfather then stepped in to protect the grandson and was also hit in the face.

Then, the elderly woman tried to intervene and was pushed onto the subway tracks as a train approached the station. The operator saw the woman fall and immediately stopped the train.

The grandmother was pulled from the tracks and medics took the elderly woman to Brooklyn Methodist Hospital. She suffered severe head injuries while the grandson also suffered a severe head injury. Both are being hospitalized. The grandfather required stitches but was released.

As of Monday night, NYPD are still looking for the suspect who fled the scene after the attack, according to PIX11. The suspect is described as being a male of light complexion, age 25-30, 5’7″, 200 pounds, and was wearing a backwards hat, black hooded sweatshirt, grey pants, white sneakers and a black backpack during the incident.
