Police are looking for the man who sucker punched a random woman after stealing beer from a deli in Queens on Saturday.

Surveillance video released by police on Monday shows the man punching the 69-year-old woman in the face as she stands outside King Deli on Sutphin Boulevard in Jamaica. The power of the blow knocks her out cold and sends her tumbling to the ground.

The woman suffered cuts and swelling on her face and head — injuries that police described as serious.

After punching the woman, the man took off with the stolen beer. Police said 28-year-old Richard Springer, also known as "Kwasi," is a suspect in the attack. He has a tattoo of the name "Emily" on his right arm. Police released an image of him on Tuesday.
