Britain's Labour Party is calling for an immediate investigation into why an anti-terror law was used to detain David Miranda, the partner of Guardian journalist Glenn Greewald, who interviewed NSA leaker Edward Snowden.
Miranda was held for nearly nine hours at Heathrow Airport under the country's terrorism act, which allows authorities to hold suspects for up to nine hours.
During that time, Miranda was allegedly questioned about the NSA and had his cellphone, laptops and memory sticks confiscated.
Miranda has returned to his home in Rio, Brazil, where he was met by Greenwald, who has vowed to continue releasing the information provided by Edward Snowden.
