Police are looking for a group of men and women they say violently attacked a man in Queens last week — knocking him unconscious — as they robbed him.

On March 31 at about 9:48 p.m., near Putnam and Seneca avenues in Ridgewood, the suspects — described as two men and two women — punched and kicked the 52-year-old victim in the face and head numerous times, according to authorities.

They then went through the pockets of his clothes and took his property, cops said.

The victim was knocked to the ground unconscious and suffered many injuries to his head, according to police. He was taken to Elmhurst General Hospital in critical but stable condition.
