Tensions between Arsenal and Tottenham Hotspur supporters reached breaking point at Saturday’s North London Derby.
One fan was pictured with blood pouring down his face from a head injury while other images showed supporters brawling outside White Hart Lane.
Two people were arrested over the fighting.
A spokesperson for the Metropolitan Police said: "The two individuals were detained separately, in unconnected incidents, around 12.20pm at the junction of High Road and Park Lane.
"They have been taken to north London police station where they currently remain.
"An appropriate policing plan is in place for the event."
This is not the first time the derby has seen problems with fans’ behaviour.
