London (CNN) -- A 61-year-old man has been arrested in London in connection with an inquiry into phone hacking, the Metropolitan Police said Wednesday.
The man, who has not been named, was arrested by officers involved in Operation Weeting, as the phone-hacking probe is known, on suspicion of unlawful interception of communications and conspiring to intercept communications.
Police have made 12 arrests as they investigate claims of phone hacking and bribery by staff at the now-defunct News of the World newspaper, part of Rupert Murdoch's News Corp. empire.
Those arrested include Andy Coulson, a former News of the World editor who subsequently worked for Prime Minister David Cameron, and Rebekah Brooks, the former chief executive of News International, the British arm of News Corp. which published the paper. Both have been released on bail and deny wrongdoing.
Journalists from News of the World stand accused of hacking into the voicemail of people ranging from celebrities to crime victims, and of illegally paying police for information.
The scandal has led to the resignation of executives at News International and of senior police officers.
News of the World was shut down last month after outrage over claims that the voicemail of missing British teenager Milly Dowler was among those hacked, potentially hindering the police investigation into what turned out to be a murder case.
