| The twin suicide attacks in Lahore on Tuesday were planned four months ago, investigators said on Wednesday. They said the Punjab Home DepartmentÂ’s Special Investigation Unit had been working in a house in Model Town. They said the SIU office had been shifted to another location in November 2007 after militant Qari Zaffar of the banned Hizbul Mujahideen, escaped from the SIU office, and threatened to blow up the investigation centre. The house was then rented to Shahzad Qayyum, a Peshawar businessman. Shahzad said the former SUI in-charge had visited their house along with police officials and briefed them. |
