Norfolk Police have been counting the cost of Halloween, revealing that 25 people were arrested.
On Friday night five officers were also injured whilst detaining a man for being drunk and disorderly.
And on Saturday, 14 anti-social behaviour dispersal notices were issued.
People were arrested for a variety of offences, including public order and affray. Officers also dealt with 10 assaults and one sexual offence. No serious injuries were recorded.
Officers closed Prince of Wales Road at 1.30am on Sunday morning because of the large number of people on pavements in the area.
Assistant Chief Constable Sarah Hamlin said: 'Operation Impact took place on Saturday evening and our key message was around supporting the vulnerable and ensuring people got home safely.
'A number of factors meant that an unanticipated volume of people were out in the city centre (of Norwich) including Halloween, the Rugby World Cup Final and pay-day weekend. This meant that many pubs and clubs hit maximum capacity much earlier than usual.
'This is one of the busiest nights we've seen for public order policing in recent years and additional resources were allocated from around the county to assist. Subsequently, this will affect how we police this weekend in the future.
'Officers were presented with challenges, however, working alongside venues and staff from the bars and clubs themselves; we were able to deal with those challenges appropriately and effectively, while keeping arrests to a minimum.
'As well as the Norfolk Constabulary officers, I'd like to thank members of our Special Constabulary for their support on the night and also the four support organisations that were assisting throughout the evening, including: SOS, Safe Haven, Street Presence and Street Partnership.'
