LONDON  - British police are investigating The Times newspaper over claims that it hacked emails, it emerged Thursday, following the scandal over phone hacking at its sister paper the News of the World. The revelation follows the admission by the editor of The Times, James Harding, to an inquiry into press ethics last month that one of his journalists had hacked the email account of a police blogger to try to expose his identity. Tom Watson, a lawmaker from the opposition Labour party, wrote to London’s Metropolitan Police to complain about the newspaper’s behaviour and published the letter he received in reply.
