A man had part of his ear bitten off when he challenged a group of rowdy teenagers on Portsmouth seafront.
The 36-year-old victim was sat in a shelter between the life guard station and the Pyramids when one of the youths threw a stone at him.
He challenged the group and one of them punched him and bit the top of his left ear off before fleeing.
The man was taken to hospital after the attack on Friday and underwent surgery to sew the piece of ear back on.
The group was a mix of boys and girls.
The main offenders were described as a 17-year-old boy, about 5ft 8ins with blonde hair and skinny build, and another 17-year-old boy, about 5ft 8ins tall with ginger hair and of a chunky build.
