Circle line Party?

BoJos at Westminster Station

The capital's underground network returned to normality following chaotic scenes caused by revellers partying on the Tube ahead of a midnight booze ban which came into effect on the 1st June 2008.

Police made a total of 17 arrests during the evening and were forced to close six stations on the Circle Line when high spirits got out of hand.

People are now barred from drinking alcohol on London Underground, buses, Docklands Light Railway and tram services in the capital. It is also illegal to carry opened lager cans on capital's transport network.

The measures were announced earlier this month by new London Mayor Boris Johnson.

In advance of the ban coming in, social networking websites such as Facebook advertised a "last chance" party. But what started as a fun way to usher in the new laws turned sour as thousands of revellers poured into London's Tube stations.

Four train drivers and three other London Underground staff were assaulted during the evening. The tyres of a police vehicle were slashed, two officers assaulted and another was injured amid chaotic scenes.

Superintendent Ellie Bird, of British Transport Police, said: "This was an unfortunate end to what was intended to be a fun event. The arrests were made following sporadic outbreaks of disorder which is very disappointing given the intention of the organisers was that this should not be a disorderly or disruptive event."
