The terrorist behind the Peshawar mosque explosion that killed more than 100 people managed to slip through the net dressed as an officer, police chief Moazzam Jah Ansari told reporters.
Authorities have released CCTV footage showing him dragging his motorcycle towards the police compound, making it appear as if it had broken down.
Authorities say they have identified the attacker as a member of a militant group and are approaching his associates who helped plan one of the deadliest attacks in Peshawar.
