Counterterrorism police are questioning a friend of Michael Adebolajo, one of two men suspected in the savage killing of a British soldier.
Abu Nusaybah was arrested following a BBC interview in which he said Adebolajo had changed after returning from a visit to Kenya where he claimed he had been physically and sexually abused in detention.
The BBC said Nusaybah was arrested by police outside its studios Friday night immediately after recording the interview. Metropolitan Police confirmed that a 31-year-old man was arrested.
Nusaybah told the BBC that Adebolajo had been detained, questioned and abused by security forces in Kenya during a trip there in 2012. Nusaybah also claimed the U.K.'s security services tried to recruit Adebolajo after he returned to Britain.
