LONDON (Reuters) - British police said on Thursday that documents seized from the partner of a journalist, who has led coverage of Edward Snowden's leaks about U.S. and British electronic spying, were "highly sensitive" and, if disclosed, could put lives at risk.
Counter-terrorism detectives said they had begun a criminal investigation following a preliminary examination of the material taken from David Miranda, partner of American journalist Glenn Greenwald, after he was held for nine hours at London's Heathrow Airport on Sunday.
