A man suffered head injuries after being pushed to the floor, stamped and kicked.
The assault took place at 8.40pm on March 14 as the victim was walking along Cross Street in Luton.
The victim became involved in an argument with a group of men and one of them then pushed and punched him to the floor before stamping and kicking the victim in the head.
The group then fled the area and the victim made his way home where he called the police.
Detectives have searched CCTV which captures the assault taking place but are now asking for members of the public to help identify the man pictured.
DC Timothy Worden, who is investigating the assault, said: “This was a disgusting attack which left the victim with a rather nasty injury to the back of his head. I would urge anyone who witnessed the incident or knows the offender to get in contact with Bedfordshire Police.”
