Indian police on Monday were granted a further two-week extension to hold and question the lone surviving gunman captured during the Mumbai terrorist attacks, a senior officer told AFP. A judge granted a request to hold Ajmal Amir Iman -- also referred to as Kasab -- during a brief hearing in the city, said the officer in charge of the investigation, Crime Branch chief Rakesh Maria. "We have got custody up to February 2," Maria said. Maria has previously said that police were 'quite hopeful' of bringing formal charges against the alleged militant before January 24 -- 60 days after Iman was initially detained. Police have up to 90 days from the date of Iman's arrest to file charges.
