A protest has been held on Sunday in support of a terror suspect facing extradition to the US.
Mr Ahmad, in green, is fighting extradition to the US
Barbar Ahmad, from Tooting, south London, is accused of trying to raise funds for terrorism via websites and e-mails.
He is being held at Woodhill prison in Milton Keynes, Buckinghamshire, where family and friends have been demonstrating.
His supporters claim the extradition moves are politically motivated.
He had previously been arrested under anti-terrorism laws in December 2003 and released without charge but was arrested again on 5 August.
His wife, who spoke to BBC News on condition of anonymity, said: "As far as I am concerned he is a British political prisoner.
"He is innocent and he should be released."
His father Ashfaq Ahmad said his son was law abiding and described the accusations as "wild and ridiculous lies".
Mr Ahmad, an IT administrator at Imperial College London, was arrested in South Kensington, west London, under anti-terror laws.
He faces four charges over offences alleged to have taken place between 1998 and 2003.
Among them are claims he used websites and e-mail to raise money and support Taleban fighters in Afghanistan.
America also claims he had plans for a US Navy battle group in the Gulf, including comments on how ships were vulnerable to attack.
He is also said to have had e-mail links to a Chechen Mujahideen leader who planned the Moscow theatre attack in October 2002 in which 129 people died.
During an extradition hearing at Bow Street Magistrates' Court earlier this month, a US government lawyer said Mr Barbar bought 100 camouflage suits and tried to buy large amounts of chemicals.
But Edward Fitzgerald QC, defending, said there were concerns over whether Mr Ahmad would get a fair trial in the US.
The extradition hearing has been adjourned until 16 December.
