Radicalized in London?

It turns out that the terrorist, Umar Farouk Abdulmutallab, who attacked the Delta airliner on Christmas Day, was the president of the Islamic Society at University College London when he was there, according to this New York Times article: Quesions Arise on Why Terror Suspect Was Not Stopped.

There's a suggestion that he became radicalized in London:

A cousin of Mr. Abdulmutallab, who spoke on condition of anonymity because he did not want to offend the family, said in an interview on Sunday that there was no sign of radicalism in Mr. Abdulmutallab while he was growing up in Nigeria, though he was devout.
“We understand that he met some people who influenced him while in London,” where Mr. Abdulmutallab studied engineering, the cousin said. “He left London and went to Yemen where, we suspect, he mixed up with the people that put him up to this whole business.”
He added: “I think his father is embarrassed by the whole thing, because that was not the way he brought the boy up. All of us are shocked by it.”
