England fans who cause trouble before country's clash with Serbia face being thrown into a 'drunk tank' cell that can hold 50 people

England fans who cause trouble before Sunday's match face being thrown into a 'drunk tank' cell that can hold 50 yobs.

Police in Gelsenkirchen, where the game kicks off at 8pm, showed two temporary metal cells – one for England fans and one for Serbians – to The Mail on Sunday.

The ausnuchterungszelle – which translates as 'sobering-up cells' – have been installed in a security crackdown for the match, which German police have classed as 'high risk' because of Serbian and English thugs' past behaviour.

'If someone has become extremely aggressive, or has attracted attention, we will use these facilities,' police spokesman Stephan Knipp said.

'We would temporarily accommodate them until everything is sorted out.

'We have these facilities for roughly 100 people, but if this capacity is exceeded and exhausted, in this worst case scenario we would take other people who have been detained to nearby Recklinghausen.

Officers have been training specially for Sunday's match, with an extra 150 riot police stationed around Veltins-Arena stadium, home ground of FC Schalke.

The specialist England Football Policing Unit, a team of police officers and police staff dedicated to supporting other police forces in reducing incidents involving UK supporters, have also flown into Dusseldorf Airport ahead of England's match against Serbia.

Fans will be served half-strength beer in another attempt to prevent trouble.
