Olympic Clock unveiled

Detectives have now made 49 arrests in a crackdown on ticket touts ahead of the London 2012 Games.

Arrests have been made for a range of crimes including fraud, money-laundering and handling stolen goods since Scotland Yard's specialist squad was set up in June.

A 5 ton clock more than 6 metres high is unveiled in Trafalgar Square tonight.

It's going to countdown to the Olympics as tickets for the Games go on sale.

Over 2.5 million people have signed up for them.

It looks like hotels in London are already putting prices up ahead of next year's Olympics.

The Financial Times reports one four-star is quoting prices of 11 hundred pounds a night, when usually it's a couple of hundred.
