British police investigating a phone-hacking scandal at Rupert Murdoch's defunct News of the World have arrested a senior Hollywood reporter at the tabloid, James Desborough, a source with knowledge of the situation said.
Police said they had arrested a 38-year-old man on suspicion of conspiring to intercept communications after arriving at a south London police station on Thursday morning by appointment.
Desborough joined the News of the World in 2005 as a show business and news reporter and was promoted to become U.S. editor, based in Los Angeles, in 2009. He worked for the News of the World up until it closed last month.
The Guardian newspaper's website said the allegations were believed to relate to events before Desborough was sent to the United States.
U.S. agencies are investigating whether the News of the World's phone-hacking activities extended to the United States. So far, they have not found evidence that they did.
The arrest is the 13th this year in an inquiry that has rocked the News of the World's parent company, Murdoch's News Corp , and has had far-reaching implications for the British establishment.
A spokeswoman for News International, News Corp's British newspaper arm, said the company was cooperating fully with police and could not comment further because of the police investigation.
Former News of the World editor and Murdoch favourite Rebekah Brooks and Britain's top two policemen have resigned over the allegations, while Murdoch and his son James have been quizzed in parliament.
James Murdoch, who runs News Corp's non-U.S. operations, may be recalled to face further questions after two senior former News International executives called his evidence into question.
A letter published this week suggested that many senior figures at the News of the World were aware of phone hacking, undermining the media company's defence that the practice was the work of a rogue reporter.
