Police are looking for the man who slapped an elderly woman so hard he knocked her out and sent her to the hospital in Jamaica on Saturday morning.

Video obtained by NBC4 shows a man who officers identify as Richard "Kwasi" Springer, 28, walk up to the 69-year-old woman outside a bodega on Sutphin Boulevard at 8:10 a.m. and smack her in the face, sending her sprawling on her back, the back of her head banging into the pavement.

The man who is allegedly Springer staggers off around the corner. The victim was a stranger to her attacker, according to reports. She was on her way home from church, family members told ABC7.

Police say that the woman suffered a serious head injury. Paramedics drove the woman to Jamaica Hospital, and she is listed in stable condition. ABC7 reports that the victim is a grandmother, and suffered a brain hemorrhage.

Doctors removed a piece of the victim's skull and are going to replace it with a plate, her daughter told the station.

Springer allegedly stole beer from the store, King Deli, moments before the attack, and video obtained by ABC shows a man believed to be him fighting with deli workers.

Springer's last known address was in South Jamaica.

Police say he stands 5-foot-11, weighs 175 pounds, has brown eyes, hair in corn rows, and a tattoo on his right arm that reads "Emily."

He was last seen wearing a black sweatshirt, blue jeans, and black boots.
