British PM's former spokesman arrested

LONDON - British Prime Minister David Cameron's former spokesman has been detained on suspicion of committing perjury in a court case in Scotland, Scotland's Crown Office said on Wednesday.
Andy Coulson told a court case in 2010, while he was working for Cameron, that he had had no knowledge of illegal activities by reporters while he was editor of the News of the World. Coulson has since been arrested over allegations of phone hacking at the tabloid.
Coulson stood down in January 2011 after police reopened the hacking case. He has denied any knowledge of the crime.
