THREE boys have been arrested after a gang attack on a teenager at a skate park.

The attack happened at 1.40pm in Avenue de Chartres in Chichester on October 16.

Police believe as many as six may have been involved in the unprovoked assault, which left a 17-year-old student needing hospital treatment.

He had suffered multiple cuts and bruises to his face. Officers have appealed for information to help catch the other three.

PC Tom Van Der Wee said: “We believe about six boys were involved in this unprovoked attack and we are keen to hear from anyone who saw what happened.

“This was a busy road at a busy time of day and we believe a number of people witnessed the assault.”

Anyone with information should call 101 and quote 689.
