The conductor of the bus in which the Ghatkopar blast took place on December 2, 2002, on Thursday turned hostile in a special pota court. Dattatraya Shelkar said he had not identified an accused in test identification parade as claimed by police. The statement came as another court granted bail to four senior Mumbai Crime Branch officials, in the alleged custodial death of POTA accused Khwaja Yunus, arrested for his alleged role in the blast. —PTI
