Police arrested two Indian men accused of illegally buying mobile phone cards used by the gunmen in the Mumbai attacks, AP quoted police as saying. It was not immediately clear whether the two had prior knowledge of the attacks, which killed 171 people. Police said another Indian citizen who was arrested in February in northern India carrying hand-drawn sketches of hotels, the train terminal and other sites that were later attacked was being brought to Mumbai for renewed questioning. One of the arrested men allegedly bought SIM cards by providing fake documents, including identification cards of dead people, senior police official Rajeev Kumar said Saturday in the eastern city of Calcutta. The SIM cards were later used by the gunmen. Police said they were still investigating how the 10 gunmen obtained the SIM cards, and declined to offer more details.
