Cameron aide arrested in 'child abuse imagery' inquiry
One of David Cameron's aides has been arrested on suspicion of an offence "relating to child abuse imagery", Downing Street has said.
Patrick Rock resigned from his post on 12 February.
Number 10 said it had been made aware of a potential offence and immediately referred it to the National Crime Agency (NCA), which arrested Mr Rock at his home a few hours later on 13 February.
The NCA has not confirmed the arrest.
A Downing Street spokesman said that following Mr Rock's arrest, it "arranged for officers to come into Number 10 [to] have access to all IT systems and offices they considered relevant".
The prime minister was immediately informed following the discovery of potential child abuse imagery and kept updated throughout, he said.
He added: "This is an on-going investigation so it would not be appropriate to comment further, but the prime minister believes that child abuse imagery is abhorrent and that anyone involved with it should be properly dealt with under the law."
