[1] A man called Robbie Knox then thought up the idea of a Circle line party to be held at the end of the month to celebrate the last night of legal drinking on the London Underground, and spread the idea on the social networking website Facebook.

The line was suspended after several trains were damaged during the party, and a number of London Underground staff and police officers were assaulted.

Seventeen people were arrested due to disorderly behaviour and six tube stations were closed as they became overcrowded.
