Police were faced with "completely unacceptable" disorder during an "extremely busy" night in Bristol on Saturday.
Avon and Somerset Police said five people, including a 16-year-old boy, were detained after several incidents in the city.
He was arrested after an officer had a drink poured over her as she attended disorder in the Canon's Road area.
One officer said revellers visiting the city had come from Wiltshire and Wales.
City centre has been extremely busy with some people travelling as far as Wales and Wiltshire to enjoy #Bristol nightlife. Unfortunately colleagues have been assaulted by being punched or having drinks thrown over them 😐 Lots of detainees waking up in Custody this morning. pic.twitter.com/x0Bl1rihhH— PC Joe Iles (@ASPJoeIles) August 29, 2021
