The policing operation during the Download music festival in Leicestershire was "a great success".
Leicestershire Police made a number of arrests. The force says the main issue it was faced was theft from tents.
The event attracted sell-out crowds of up to 100,000 each day and more than 70,000 camped across 13 campsites.
Inspector Chris Brown, who was in charge of the crime prevention operation at Download, said: “We put a lot of effort into our plans this year, as we do every year, and I am really pleased with the outcome of the operation.
"We had some extra challenges this year with the wet weather on Wednesday and Thursday which led to an unprecedented number of people arriving at the same time causing long traffic tailbacks particularly on Friday afternoon.
