A teenager was stabbed in the hand after being attacked by a gang of youths on Eastbourne beach.
The group of seven boys and young men set upon the 17-year-old victim, who was with two friends on the promenade between the pier and the bandstand, shortly after 4pm on 10 November.
The boy was taken to the Queen Victoria Hospital in East Grinstead for treatment and has since been discharged.
Police made six arrests of suspects aged between 14 and 20, including one suspect on suspicion of wounding with intent.
All have been bailed with strict conditions, pending further investigation.
Officers have been carrying out enquiries and increased patrols in the area to provide reassurance, but are keen to speak to witnesses who may have seen what happened in a busy area during daylight.
The assault happened in the lower area of the Promenade.
Anyone with information should report it to Sussex Police online or call 101 and quote serial 751 of 10/11.
