Ai Weiwei 'ordered to turn cameras off'

Chinese artist Ai Weiwei says he has been ordered to shut down four live webcams, external at his home, which he set up as a nod to the 24-hour police surveillance he has lived under for the last year.

The artist told the BBC that he installed cameras at his desk, outside his home and above his bed to encourage transparency.

He said he was ordered turn off the camera feeds but he told Radio 4's World at One that he "won't be shut down".

Mr Ai was detained in April 2011 during a crackdown on political activists and is now banned from leaving Beijing.
