CNN host and former UK tabloid editor Piers Morgan was questioned in December in connection with a UK police inquiry into phone hacking, CNN reported Friday.Morgan said he was interviewed while in Britain by officers involved in the investigation into claims that journalists illegally hacked people's voice mail to get stories, known as Operation Weeting."In early November I was asked to attend an interview by officers from Operation Weeting when I was next in the UK," he said in a prepared statement. "This was further to a full witness statement I had already freely provided. I attended that interview as requested on 6 December 2013."London's Metropolitan Police said in a prepared statement: "A 48-year old man, a journalist, was interviewed under caution on the 6th December 2013 by officers from Operation Golding in connection with 'suspected conspiracy to intercept telephone voicemails. "He was interviewed by appointment at a South London police station and he was not arrested."Operation Golding is a strand of Operation Weeting and is specifically investigating allegations of phone interception at Mirror Group Newspapers, a Metropolitan Police spokesman said. The Daily Mirror, formerly edited by Morgan, is one of the group's titles.There have been four arrests under Operation Golding and three people have been interviewed under caution, the Met Police said. This means anything said can be given in evidence in court.
