David Miranda: 'They forced me to give my passwords'

David Miranda, the Brazilian man held under controversial anti-terrorist legislation for nine hours in London, has told the BBC he felt very threatened in relentless questioning during his detention.

Mr Miranda, the partner of Glenn Greenwald - the journalist who exposed a US electronic surveillance programme - said it was a repeated threat that he would face jail if he did not cooperate that forced him to disclose the passwords to all his email and social media accounts.
