(AP Photo, File) (Newser) – Yesterday we learned that London slaying suspect Michael Adebolajo may have been questioned by Britain's domestic spy agency, MI5, last year. Today, more questions about just how much UK authorities knew (or should have known) about the man are emerging, with news that he was detained in Kenya in 2010 on suspicion of seeking to train with an Islamist militant group associated with al-Qaeda, Reuters reports. "He was arrested with a group of five others trying to travel to Somalia to join militant group al Shabaab," says the head of Kenya's anti-terrorism police. Adebolajo was then deported to Britain. The government confirmed the information, and said it had provided assistance.
