British citizens Michael Adebolajo and Michael Adebowale, both Muslim converts, were found guilty of murdering a British soldier in Woolwich; they were not convicted on charges of attempting to murder a policeman. Prior to the murder, Adebolajo was known to authorities as an extremist; he had been radicalized by the outlawed group Al-Muhajiroun and arrested in Kenya in 2010 while trying to join Shabaab.
