British authorities dropped charges against high-profile former Guantanamo Bay detainee Moazzam Begg on Wednesday , days before he was due to go on trial on charges of attending a terrorist training camp in Syria . Begg , from Birmingham in the English Midlands , will now be freed from prison , where he has been held since March , a West Midlands Police statement said . The case was discontinued after police and lawyers for the Crown Prosecution Service reviewed new material and concluded there was no longer a realistic prospect of gaining a conviction , the statement said . Begg 's trial had been due to start on October 6 . Assistant Chief Constable Marcus Beale said : `` New material has recently been disclosed to police and CPS , which has a significant impact on key pieces of evidence that underpinned the prosecution 's case . Our criminal justice system -- quite rightly -- demands a very high standard of proof . `` I understand this is going to raise many questions . However , explaining what this newly revealed information is would mean discussing other aspects of the case which would be unfair and inappropriate as they are no longer going to be tested in court .

Qureshi accused UK authorities of criminalizing `` virtually any Muslim that has been to Syria '' and said Cage had also come under pressure to shut down . `` We hope that Moazzam 's release is a sign that the government are now willing to adopt a more measured strategy in relation to anti-terrorism policy and avoid the attempt to criminalize all dissent and crush any organization like Cage that stands up for the rule of law and justice , '' he added .
