A former news editor of the News of the World Scotland who gave evidence at the trial of Tommy Sheridan has been arrested and charged with a phone-hacking offence.
Douglas Wight has also been charged with perjury over evidence he gave at the disgraced former MSP's at the High Court in Glasgow.
The 39-year-old journalist was interviewed at Govan Police Station in the city on Thursday afternoon.
He is also accused of multiple counts of conspiracy to obtain the personal data of members of the public.
The arrest by officers from Operation Rubicon, the Scottish police inquiry into evidence that emerged during the Sheridan trial in 2010, was made public on Thursday evening.
Sheridan was jailed for three years after being found guilty by a jury of perjury during his successful defamation action against the News of the World in 2006.
He was released in January, having served just over a third of his sentence.
A spokesman for Strathclyde Police said: "Officers of Operation Rubicon of Strathclyde Police arrested and charged an 39-year-old male with perjury before the High Court in Glasgow during the trial in 2010 (for perjury) of Tommy Sheridan, the former MSP, conspiracy (in Scotland) to hack telephones (Contraventions of Section 1 of the Regulation of Investigatory Powers Act 2000), multiple charges of Conspiracy to obtain the personal data of members of the public in breach of the Data Protection Acts and individual offences under these Acts.
"A report will be submitted to the procurator fiscal at Glasgow in due course. Proceedings are now active and it would be inappropriate to comment further."
