Tabrez, a resident of Mumbra in neighbouring Thane district, was caught last week in Libya, where he had joined the terror outfit with Ali. <br/><br/>Meanwhile, ATS has written to Centre seeking more information about Tabrez and his activities in the oil-rich country and the exact role he might have played for the IS.<br/><br/>The ATS teams are making enquiries with Tabrez's family members, relatives and friends in this regard.
