Unbelievable moment a 'naked' man appears to SUNBATHE on the top of Tower Bridge

This is the unbelievable moment a naked man appears to SUNBATHE on the top of the London's Tower Bridge.

Crowds gathered on the side of the River Thames as the sun worshipper stripped off and made himself comfortable on the blue arches. Police were forced to close the world-famous landmark after the man climbed near to the top of the 213-ft high bridge at around 2pm on Saturday.
