Police have said only a "small minority" of fans behaved badly at an FA Cup match between Luton and Millwall.
The FA Cup Fifth Round tie at Kenilworth Road ended with Millwall winning 3-0.
Bedfordshire Police said seven people were arrested for public order offences.
Three men were arrested before the game.
The other arrests, including one for throwing a bottle at a police horse, were made after the game in the town centre after a short stand off between police and a minority of fans in the areas of Dudley Street and George Street.
All those arrested remain in custody pending further enquiries.
“I have been pleased with the way today’s policing operation has gone,” said Supt Linda Kelly, tactical commander for the day.
“It was an excellent partnership between ourselves, the clubs, the other forces and agencies. It is a shame that a small minority behaved badly after the game but the vast majority of fans enjoyed the occasion despite the result on the field and went away without causing any problems.
“There will be a debrief and any people we identify who did cause problems we will look to arrest at a later time.”
