(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.
