Radio 1's Big Weekend was a largely peaceful event, with just eight people arrested over the two days.
Some 50,000 people descended on Earlham Park to watch Taylor Swift, the Foo Fighters and Muse perform at Radio 1's flagship event.
Norwich Superintendant Dave Marshall said there had been four minor assaults, one mobile phone theft and one theft from a bag, which he added was low for an event of that size.
'It was a fantastic mix of people, from young children with ear defenders to grandmas and granddads,' he added.
'There were very few problems, and few alcohol related incidents.'
Some 11 people were thrown out over the whole weekend, and there were three arrests for assault, one person caught drink driving and four people who were drunk and disorderly.
