Tooting terror suspect Babar Ahmad today urged the Metropolitan Police (Met) to bring disciplinary proceedings against "all officers who were personally involved" in the alleged assault against him.

Mr Ahmad, who has been in custody for nearly seven years without trial while fighting against extradition to the United States on terror charges, has also called on Prime Minister David Cameron to ensure he be given a trial in Britain.

His pleas follow the not guilty verdicts given this morning to four Met officers - Detective Constable John Donohue, 37, and PCs Roderick James-Bowen, 40, Mark Jones, 43, and Nigel Cowley, 34 - who were accused of assault occasioning actual bodily harm.

The Met has promised to launch a misconduct review into the actions of the four policemen - but no other Met officer has been associated with any wrongdoing.

Acting Commander Carl Bussey, head of the Met's Directorate of Professional Standards, said: "The issues that have arisen out of the arrest have now been ongoing for a long time and undoubtedly this will have been a difficult seven years for all involved.

"Given the result I will now ensure a misconduct review is conducted immediately so that the [four] officers can be given a decision as soon as possible and this matter finally brought to a conclusion."

The Met paid Mr Ahmad £60,000 in damages in a civil case in 2009, conceding Ahmad had been the subject of a "a serious, gratuitous and prolonged" attack.

Upon hearing today's verdict, Babar Ahmad said in a statement read out by his father, Ashfaq Ahmad: "In 2009, the Met admitted at the High Court that I was brutally assaulted by its officers without resisting arrest.

"Today’s verdict means that no police officer has been held to account for this abuse. Therefore I urge the Met to bring disciplinary proceedings against all officers who were personally involved in the assault - and those who turned a blind eye.

"I would not have reached this point without the help of my family and years of hard work by Bhatt Murphy solicitors. I am also grateful for the support of many other people, some I know, many I’ve never met before. They all have given me the strength to fight for justice.

"The material seized from my home that morning was sent to America, leading to the request for my extradition. No British court has ever considered the strength of this evidence. As a British man, I should be given a fair trial in Britain, just as these officers have received.

"I deny any involvement in any terrorist activity and have done so under oath in this trial. I must be able to defend myself from such serious allegations in a British court, given the evidence was seized here, I was born and bred here, I have lived and worked here and I have no connection to America whatsoever.

"Mr Cameron - I’ve been in prison almost seven years, the equivalent to a 14 year sentence, yet have not been charged. My plea is simple - will you please back the British justice system and support British trials for British citizens?"

Fiona Murphy, Mr Ahmad's solicitor, added: "The criminal proceedings have taken their course and the jury has returned its verdict. We now call upon the IPCC to put its abject failures in relation to this case to one side and to give proper consideration to the misconduct aspects."

The IPCC has previously told Mr Ahmad and his family it is not able to reinvestigate the matter using its new powers - and has no powers to require the Home Office to hold an independent inquiry.

In July 2006, the IPCC published a detailed account of the way in which complaints by Babar Ahmad were handled which can be found on the IPCC website.

The family asked the IPCC to take a number of further actions; none of these are open to the Commission. The IPCC is not able to reinvestigate the matter using its new powers. The IPCC has no powers to require the Home Office to hold an independent inquiry.
