Pictured in the crowd which called for the beheading of British soldiers: Newly unearthed photo of terror suspect Adebolajo with banned extremist group Alleged killer of Lee Rigby seen marching with Muslims Against Crusaders Film from 2007 came after an extremist was arrested and held by police Adebolajo shown holding a placard 'Muslims only guilty of worshipping Allah' Group banned in 2011 after members burned poppies on Remembrance Day Raises more questions about how much security services knew about him Waving a placard protesting 'Muslims only guilty of worshipping Allah', this is believed to be Woolwich terror suspect Michael Adebolajo, marching with a group that openly called for the beheading of British troops. This new picture shows the radical, now 28, at a Muslims Against Crusaders rally, six years before he and Michael Adebowale, 22, allegedly hacked Drummer Lee Rigby to death. Dressed in white robes, pointing to the sky and yelling aggressively, he joined dozens who protested outside Paddington Green police station in West London in 2007 after a Muslim extremist was arrested. The now-banned group became famous after members set fire to poppies on Remembrance Day in 2010, and chanted 'British soldiers burn in hell'. This new picture, which is almost certainly Adebolajo, raises further questions about how much the security services knew about him. Pictured: A young man identified as Michael Adebolajo at a Muslims Against Crusaders rally in 2007, a group who had openly called for the beheading of British soldiers Drama: Hours after the shocking murder, footage emerged of this man with bloodied hands carrying a knife and a machete explaining the reasons for the killing. He has been identified as British Nigerian Michael Adebolajo, who is known by the Muslim name Mujahid Firebrand cleric Anjem Choudary had links to the group and he admits he first met Adebolajo in 2005 - two years after the alleged terrorist had converted to Islam. But in the wake of the horrifying Woolwich attack, Choudary has claimed he hadn't seen him for two years. But despite him being accused of the dreadful killing of Lee Rigby 25, he still described Adebolajo as a man of 'impeccable character'. Machinegunner Rigby was hacked to death by two attackers in Woolwich, south-east London on Wednesday at 2.20pm. Hero: Father Lee Rigby, 25, was executed by two suspected Islamic terrorists in Woolwich on Wednesday afternoon and has prompted calls for a crackdown on dangerous groups Controversial: Then Muslims Against Crusaders member Emdadur Choudhury (left) was fined £50 fine for burning a poppy and he was supported outside court in 2011 by a group of protesters (right) Response: Radical Anjem Choudary has admitted her knew Adebolajo and called him a 'pleasant, quiet guy' The new image shows Adebolajo was probably linked to Muslims Against Crusaders. Home Secretary Theresa May banned the group in November 2011 after it planned to repeat its poppy burning protest. The first one led to the conviction of Emdadur Choudhury who laughed at justice as he was handed a paltry £50 fine for setting light to poppies on Remembrance Day and yelling "British soldiers burn in hell." After hearing his penalty, which outraged war veterans, he declared: "I don't have any respect for British soldiers, and if they lose a limb or two in Afghanistan then they deserve it. You expect me to feel sorry for them? Of course I don't. Choudhury, from Bethnal Green, East London, was found guilty of using threatening or abusive words or behaviour, and at the time the court heard how he enjoyed benefits including a free council flat and almost £800 a month state handouts. Although Choudhury sneered that he would have been fined more than £50 for a parking offence, he is refusing to pay. However the bill will be picked up by his "good friend" Anjem Choudary, the notorious firebrand preacher.
