QUETTA: Security forces on Tuesday arrested a member of the Balochistan Liberation Army (BLA) allegedly involved in the murder of Chinese engineers two years ago. "Mohammad Khan, head of the BLA in Makran, was involved in the bomb blast on February 3, 2004 that killed three Chinese engineers," said an official on condition of anonymity. He said that Khan was arrested after security forces raided his hideout in Gwadar. "We have information that Khan had been appointed as commander of the BLA in Makran Division," the official said, adding that Khan had also been involved in several other bomb blasts and rocket attacks. "Khan's arrest is a major breakthrough which will hopefully give us more information about the terrorist organisation." Khan has been shifted to an undisclosed location for further investigation.
