Chelsea fans face 10 hours in Russian holding camp
Long wait: Chelsea fans will be 'firmly encouraged' to enter holding camps known as 'settling tanks' for up to 10 hours before the Champions League Final
Match tickets will be scanned at the entrance, making it "technically impossible" to then leave and re-enter the camp or the stadium at a later stage. Some fans could be in the fenced areas for up to 10 hours. Soft drinks, food and souvenirs will be available.
Police sources said: "We don't want people without visas wandering off around Moscow and getting drunk and missing their flights home."
After the game, losing fans will be put on buses to the airport. The winning supporters will be kept back for 30 minutes before also being taken to their point of departure.
Major Igor Konovalov, Moscow police public safety department chief, said: "It's a normal practice. We use them [camps] in our country and the fans call them 'settling tanks'."
In Russian football "settling tanks" are controversial. In one instance 5,000 fans were provided with only two toilets and surrounded for over three hours without food or drink.
Travelling British police will help Russian officers monitor the event. Chelsea are even hiring bilingual Russian-speaking stewards to accompany their fans and the mayor's office is drafting in English-speaking volunteers to help.
But Maj Konovalov warned that Russian police would crack down on any fighting.
He said: "It doesn't matter who comes here - even a bunch of Penguins. If our laws are violated we'll take full measures allowed by our law to clampdown. We will not differentiate."
