I’ve covered this before:
– Cameron aide Patrick Rock arrested over allegations relating to child porn (Telegraph, March 4, 2014):
Advisor to No 10 helped to draw up government policy on online pornography filters
One of David Cameron’s closest aides has been arrested on suspicion of offences relating to child pornography.
Patrick Rock, who was one of the government’s advisors on policy for online pornography filters, was arrested last month after police examined computers in No 10 Downing Street.
Mr Rock resigned as a policy advisor to the Prime Minister soon afterwards.
No 10 said he was arrested last month “a few hours” after Downing Street contacted police.
The former deputy head of the No 10 Policy Unit has been close to Mr Cameron for two decades. The two men worked for Michael Howard when he was Home Secretary in the 1990s.
