Police are on the hunt for four suspects who they said were involved in a violent robbery in Queens late last month.

The attack took place on March 31 near Putnam and Seneca avenues in Ridgewood just before 10 p.m., police said.

According to investigators, the suspects – three men and one woman – punched and kicked the 52-year-old victim in the face and head until he was unconscious.

Police said the suspects went through the victim’s clothing and stole unspecified property.

The victim suffered lacerations to his head and was taken to Elmhurst Hospital Center in critical but stable condition, authorities said.

On Monday, police released surveillance images of the four suspects.

Anyone with information on the incident is urged to call Crime Stoppers at 800-577-8477.
