A top British Prime Minister advisor, who helped design the country’s controversial Internet filtering program, has been arrested for possessing child pornography. Patrick Rock was arrested at his home a day after Prime Minister David Cameron’s office learned about the investigation.

“This is an ongoing 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,” said a spokesperson.

Britain has come under fire for its Internet filtering program, which can inadvertently block sensitive culture topics that overlap with common porn terms. The program accidentally “led to the creation of filters that not only cover hardcore pornography, but hate speech, self-harm, drugs, alcohol, tobacco, dating, nudity, violence, gambling, social networking, file-sharing, games and more,” explained Wired UK.

Despite the embarrassing arrest, there is no announced plan to revise the Internet filtering program. “Patrick Rock was one of a number of advisers and officials involved in dealing with this issue but the work was led by somebody else, and decisions were taken by ministers.”
