LONDON - British police are examining whether Guardian newspaper staff should be investigated for terrorism offences over their handling of data leaked by Edward Snowden, Britain's senior counter-terrorism officer said on Tuesday.
The disclosure came after Guardian editor Alan Rusbridger, summoned to give evidence at a parliamentary inquiry, was accused by MPs of helping terrorists by making top secret information public and sharing it with other news organisations.
The Guardian was among several newspapers which published leaks from US spy agency contractor Snowden about mass surveillance by the National Security Agency (NSA) and Britain's eavesdropping agency GCHQ.
Assistant Commissioner Cressida Dick, who heads London's Specialist Operations unit, told MPs the police were looking to see whether any offences had been committed, following the brief detention in August of a man carrying data on behalf of a Guardian journalist.
Security officials have said Snowden's data included details of British spies and its disclosure would put lives at risk. Rusbridger told the committee his paper had withheld that information from publication.
"It appears possible once we look at the material that some people may have committed offences," Dick said. "We need to establish whether they have or they haven't."
David Miranda, the partner of journalist Glenn Greenwald who brought the Snowden leaks to world attention, was questioned under anti-terrorism law when he landed at London's Heathrow Airport en route from Berlin to Rio De Janeiro, Brazil, and computer material he was carrying was seized.
MPs put it to Rusbridger that he had committed an offence under Section 58A of the Terrorism Act which says it is a crime to publish or communicate any information about members of the armed forces or intelligence services.
"It isn't only about what you've published, it's about what you've communicated. That is what amounts, or can amount, to a criminal offence," said committee member Michael Ellis.
Asked later by Ellis whether detectives were considering Section 58A offences, Dick said: "Yes, indeed we are looking at that."
Earlier on Tuesday, the Guardian published a letter of support from Carl Bernstein, the US journalist who helped expose the Watergate scandal in the 1970s.
Bernstein, 69, said Rusbridger's appearance before the committee was a "dangerously pernicious" attempt by British authorities to shift the focus of the surveillance debate from excessive government secrecy to the conduct of the press.
