( CNN ) -- Umar Farouk AbdulMutallab , who is accused of trying to detonate an explosive on an international flight into Michigan on Christmas Day last year , was not radicalized while he was a college student , according to a report released Friday . The study was conducted by a panel set up by the University College London ( UCL ) , where AbdulMutallab was enrolled in the mechanical engineering department between September 2005 and June 2008 . But , said the school , the review was done by an independent panel . `` The inquiry panel has found no evidence to suggest that Umar Farouk Abdulmutallab was radicalised while at UCL , '' the report said . `` There is evidence that UCL was , well in advance of the Christmas Day 2009 incident , taking steps to strengthen its student support processes . '' The report , however , recommended that the school better monitor invitations to visiting speakers , scrutinize student events , and consider whether there is a need for training staff so they can better deal with students who are cause for concern . A former friend of Abdulmutallab told CNN in December that the Nigerian national became more devout about his Muslim faith while attending the university in London . `` In London he isolated himself from some of his former friends , '' Kwesi Brako told CNN . `` He became much more serious about his religion . '' Brako , a Christian , was in the same year as AbdulMutallab at the English boarding school they attended in the western African nation of Togo and said they were close friends . In the fall of 2005 , he moved to England at the same time as AbdulMutallab to start university . But the two friends , who attended different schools , lost touch while in London . AbdulMutallab became increasingly involved in the Islamic Society of UCL -- one of Britain 's premier universities -- quickly becoming its vice president and threw all his energies into this new role , Brako said . Brako kept up with AbdulMutallab through mutual friends in the British capital . In June 2006 , AbdulMutallab became president of the UCL Islamic Society , CNN learned . `` He started wearing traditional Muslim robes with trousers rolled up around the ankles , '' said Brako , `` Even in the winter he wore sandals . '' In Britain , this style of dress is often associated with Muslims espousing a hardline-fundamentalist form of Islam . At high school in Togo , Brako recalls that AbdulMutallab usually wore jeans and a T-shirt . The Nigerian is the fourth president of a London Islamic Society to face terrorist charges in three years . One of them is awaiting retrial , having escaped conviction for involvement in the 2006 liquid bomb plot to blow up airliners bound for the U.S. , a precursor to the Christmas plot . AbdulMutallab is accused of trying to set off a bomb hidden in his underwear aboard a plane from Amsterdam , Netherlands , to Detroit , Michigan , on December 25 , 2009 . He faces six federal charges , including attempted use of a weapon of mass destruction and willful attempt to destroy an aircraft . He has pleaded not guilty to charges of trying to blow up the Northwest Airlines plane . During a hearing in September , he asked the judge : `` If I want to plead guilty to some counts , basically , how would that go ? '' He also said he wanted to represent himself . The next court date in AbdulMutallab 's case is expected later this month .
