Forty-eight England fans suspected of being potential football hooligans have been detained by UK police at ports and airports.
The moves come ahead of the World Cup qualifying game with Germany in Munich.
The news of the arrests comes as Munich police reveal that they are expecting around 1,000 violent German fans to travel to the game.
In Kent, 20 men are to appear before Folkestone magistrates to decide whether they should be subject to travel banning orders.
In addition, three known hooligans were stopped from flying to Germany by police at Manchester Airport.
Another eight fans, men aged between 29 and 41, were stopped at Birmingham International Airport as they tried to board a flight to Prague in the Czech Republic.
A 23-year-old man from Wolverhampton was stopped at the same airport as he tried to board a flight to Prague.
And Essex police detained another three fans this morning at Stansted airport.
The new Football Disorder Act in Britain allows officers to apply for a magistrates court order banning suspected troublemakers from travelling abroad.
