A teenage boy has been arrested on suspicion of assaulting an emergency worker during anti-immigration disorder in Thetford.
Tensions flared in the Norfolk town last week when people attempted to storm homes linked to asylum seekers and police officers were assaulted in three nights of unrest.
The force said on Monday that two further arrests have been made "in connection with violent disorder seen in Thetford on Wednesday" and that people should expect more will follow.
Norfolk Police said the teenage boy was arrested on Sunday on suspicion of assaulting an emergency worker.
The boy was taken to Bury St Edmunds Police Investigation Centre for questioning and has since been released on bail until 4 October.
A man in his 20s was also arrested on Sunday on suspicion of assaulting an emergency worker, possession of a class B drug and possession of a class A drug.
He was taken to Wymondham Police Investigation Centre for questioning, where he remains, police said.
Deputy Chief Constable Dave Marshall said officers were continuing to review footage from the disorder in an attempt to identify those "responsible for committing offences".
He added that "people should expect further arrests".

DCS Marshall thanked "the vast majority of the public who have helped to maintain calm and order in the town".
Norfolk Police said increased policing powers will continue to be in place in Thetford until 4pm on Tuesday, including Section 34 of the Anti-Social Behaviour, Crime and Policing Act 2014.
The instrument allows for certain policing figures to authorise dispersal orders.
