File picture: Len Duvall, former chairman of the Met Police Authority

A man held on suspicion of looting a mobile phone store in the riots is the son of a former police boss, it emerged today.

Mark Duvall, 26, was arrested on Friday in connection with an attack on a Vodafone shop in Woolwich, South London.

His father Len was chairman of the Met Police Authority and is leader of the Labour Group on the London Assembly.

Last week Mr Duvall OBE, the London Assembly member for Greenwich and Lewisham, called for public help to track down the rioters.

He said: ‘I’m dismayed and outraged by the mindless violence, theft, criminal damage and risk to life we have seen in Greenwich and Lewisham and around London.

‘I’m urging anyone with information, families and friends who might know people caught up in all this, to speak to the police.’

Scotland Yard have confirmed a 26-year-old was arrested on suspicion of burglary and has been released on bail.

A source told the Sunday Mirror: ‘Len knows all the senior officers. This is a bit of a nightmare.’
