Five people have been arrested at Nottingham Forest's football match against Derby County.
One person was arrested for pitch invasion, one for trying to enter the ground drunk, one for a drugs offence and two for public order on Wednesday.
A Nottinghamshire Police spokesman said officers also acted on intelligence indicating about 100 rival fans were planning to meet before the game.
The "organised disorder" on Maid Marion Way was successfully prevented.
Match commander Supt Mark Holland from Nottinghamshire Police said: "Overall, the vast majority of fans were extremely well behaved and were able to enjoy what was a great game between the two teams."
Nottingham Forest beat Derby County 5-2.
