Three police officers were taken to hospital following a mass brawl involving up to 20 people at a popular seaside holiday park.
Two Pcs - a man and a woman - were sent to reports of fighting at Pontins in Camber, near Hastings, East Sussex, just after 1.30am on Saturday.
When they arrived, the officers were confronted by a group of between 15 and 20 people who attacked them, Sussex Police said.
Captor spray had to be used by the officers to control and disperse the suspects who fled into the site before other police colleagues arrived.
A search of the area led to six men and a woman, all from north London and aged between 19 and 49, being arrested on suspicion of affray and assault.
The two Pcs and a third officer who were injured during the arrests were treated for cuts and bruises at the Conquest Hospital in St Leonards before being discharged.
The men and woman who were arrested were freed on police bail until November 19, pending further inquiries.
