The Jammu and Kashmir Police on Thursday said the audacious attack and subsequent escape of a Pakistani terrorist from a Srinagar hospital two days back was a well planned and executed conspiracy that threw open chinks in the security setup. Director General of Police (DGP) S.P.Vaid said the militant attack and subsequent escape of Naveed Jat alias Abu Hunzullah on February 6 from the SMHS hospital were not possible without connivance at the Srinagar Central Jail. "A SIT headed by a Superintendent of Police is looking into this incident. I believe a magisterial probe is also being ordered to ascertain all that led to the attack and the subsequent escape," Vaid said.
