Police are appealing for witnesses after a 15-year-old boy was attacked in Bognor.
The victim was kicked and punched by four other boys in Hotham Park about 8pm last Friday (August 5) before the suspects made off from the scene.
Police searched the area but were unable to find the boys.
All four suspects were boys of a similar age to the victim and were wearing balaclavas. Three of the them were wearing black Nike tracksuits and one was wearing a blue tracksuit.
Detective Sergeant Molly O’Malley from the Coastal Criminal Investigations Department said:
“The victim has suffered serious physical injuries requiring surgery and rehabilitation, an impact which will no doubt remain with him for the rest of his life.
“We are seeking information from anyone who was in Hotham Park on Friday evening and who may have witnessed the assault or the suspects leaving the scene.”
