Sources said that Muhammad Tariq, a railway police constable, intercepted a man draped with a shawl at the station entrance and tried to check him with a metal detector. The man refused to comply and fled. Constable Tariq called for backup and started chasing the suspect. He was followed by head constable Liaqat Ali, and constables Abdur Rasheed and Muhammad Rafi. The suspect ducked into a graveyard and began firing at the police. Tariq was hit in the torso and died instantly.Locals rushed to the spot to aid the policemen, who were unarmed. After a call for help, some armed private security guards took up positions around the graveyard and called for surrender. Five minutes later, the trapped militant surrendered and was handed over to the B-Division police station. Sources said that during the initial interrogation, the detainee stated that his name was Ali Imran and worked for Sipah-e-Muhammad. He also revealed the locations of other militants, said sources, adding that Sheikhupura police teams had begun operations to round them up.
