At least 180 football hooligans have been warned by the Met to surrender their passports after receiving banning orders.
The police have required football fans to surrender their passports by June 1 at the latest.
The warning comes ahead of the Euro 2016 competition that is being hosted by France.
Letters have already been sent to those subject to a banning order, reminding them of their legal obligation to surrender their passport.
There are 180 people who the police are targetting.
Superintendent Jon Williams from the Met's Public Order Unit said: "Violence and hooliganism will not be tolerated in football and these bans are imposed to ensure that the real fans can go and watch football games without fear of violence.
"Anyone who is on a banning order needs to realise that if they fail to hand in their passport to their designated police station within the timeframe can expect to be arrested.
"If you are arrested for failing to surrender your passport you will be brought before the court which could result in a lengthy extension to your ban."
