Three men were arrested during a protest outside The Bell Hotel in Epping on Friday, after the Court of Appeal overturned a temporary injunction that blocked asylum seekers from being housed there.
Essex Police said the men were arrested on suspicion of different offences - one for violent disorder, one for assaulting a police officer, and another for drink-driving. Two police officers were injured, though not seriously.
Assistant Chief Constable Glen Pavelin said that while most protesters had participated safely, "the right to protest does not include a right to commit crime".
The court judgement means that 138 asylum seekers staying at the hotel will not be forced to leave by 12 September.
Explaining the Court of Appeal decision, Lord Justice Bean said the initial injunction - issued by the High Court - was "seriously flawed in principle".
