A former news editor at the News of the World Scotland has been arrested and charged in connection with the perjury trial of former MSP Tommy Sheridan.
Douglas Wight, 39, has been charged with perjury, conspiracy to hack telephones and multiple charges of conspiracy to obtain personal data.
Strathclyde Police said that Mr Wight was detained as part of Operation Rubicon.
A report will be sent to prosecutors who will decide how to proceed.
Mr Wight, who lives in London, arrived at Govan Police Station in Glasgow at about 14:00 to be interviewed, at the request of Strathclyde Police.
It is understood he left the station late on Thursday night and is not expected to appear in court on Friday.
Sheridan was awarded £200,000 in damages from the News of the World in 2006 after it printed allegations that he had committed adultery and visited a swingers' club.
After the court action, the former MSP and his wife Gail were charged with perjury.
She was acquitted during the subsequent trial but Sheridan was convicted in December 2010.
He has since been freed after serving just over a year of a three-year sentence.
