British police have arrested a man suspected of phone-hacking, the 16th person detained in the scandal involving the now-defunct News of the World tabloid owned by media mogul Rupert Murdoch.

Police say they detained the 35-year-old man Wednesday but gave no further comment on the arrest.

In July, Murdoch closed down News of the World, once Britain's most popular Sunday paper. More than a dozen of the tabloid's journalists and executives have been arrested over claims that they regularly intercepted mobile phone messages and illegally paid police for tips.

Separately, the Guardian newspaper said police have questioned one of its reporters about an alleged leak of information from the investigation into the phone-hacking scandal.

The scandal has led to the arrest of former News of the World editors Rebekah Brooks and Andy Coulson. Coulson went on to head communications for British Prime Minister David Cameron before resigning in January.

The two are yet to face criminal charges.

Last week, Murdoch's British subsidiary, News International, confirmed it is conducting a broad inquiry into reporting practices at all of the company's British newspapers. The review of journalistic standards will look at News International publications — the Times, its sister-publication the Sunday Times and Britain's biggest-selling daily newspaper, The Sun.

News International is a wholly owned subsidiary of Murdoch's worldwide media conglomerate, News Corporation.
