The stars of The Road To Guantanamo were arrested under anti-terrorism legislation at Luton airport, it has been revealed.

The men were returning from the Berlin Film Festival at the time, having won a Silver Bear award for their film.

"Six people were stopped under the Terrorism Act. This is something that happens all the time and obviously at airports and train stations," said a spokeswoman for Bedfordshire police. "There is a heightened state of security since the London bombings. Public safety is paramount."

Actors Farhard Harun, Shafiq Rusul and Rhuhel Ahmed were detained, with Ahmed alleging that he was verbally abused by a police officer during the questioning. Bedfordshire police say they plan to issue another statement regarding Ahmed's concerns soon.

The film itself concerns the story of the Tipton Three, who went to Pakistan to arrange a wedding but ended up in Afghanistan, believed to be terrorists. They were sent to Guantanamo and were released in 2004 without charge.
