British police said on Thursday that they had arrested three Muslim men suspected of traveling to Pakistan for terror training. Richard Dart, 29, Imran Mahmood, 21, and Jahangir Alom, 26, allegedly traveled to Pakistan between 2010 and 2012 “with the intention of committing acts of terrorism or assisting another to commit such acts,” said Metropolitan Police in a statement. Police also alleged the three men counseled others on how to travel to Pakistan and find safe locations to train. Dart was the subject of a recent BBC documentary, My Brother the Islamist, in which filmmaker Robb Leach, Dart’s stepbrother, tried to figure out why Dart had become a hardline Islamist. Police said the arrests are not related to the Olympics.
