Ibrahim (The Crusade)
From Tardis Wiki, the free Doctor Who reference
Ibrahim was a bandit during the Crusades. In 1190, he captured Ian Chesterton, believing him to be hiding money, and threatened to murder him by making him appetising to an ant colony. Ian tricked Ibrahim into helping him get freed, then forced him to take him to Lydda and help rescue Barbara Wright. (TV: The Crusade)
