A police guard murdered the 27-year-old son of deputy inspector general (DIG) of Peshawar police at their residence in Karachi's Defence Housing Authority (DHA) early Saturday, police said.

Umair Shahab, son of DIG inquiries and inspection Peshawar Shahab Mazhar Wali, was strangled to death by Faqir Mohammad, a police guard stationed for security at their house in Khayaban-e-Seher of DHA Phase 6 during a scuffle.

After killing Umair, the suspect locked himself in a room. Police broke down the door and took him into custody.

According to police, Faqir Mohammad in his confessional statement said he had intended to ask Umair's mother to give him Rs200,000, which he wanted to send to his family in his native village. When he tried to approach the woman to ask her for the amount, he was accosted by Umair, who stopped him from going upstairs to his mother's room.

During the scuffle that ensued between the two, the guard put a noose around Umair's neck and strangled him to death at around 2:30 in the morning.

Police reached the house after the incident and started an investigation into the murder after arresting the security guard.

A police official speaking to DawnNews said Faqir Mohammad hails from Sindh's Kashmore district and was serving as a security guard at DIG's Shahab's house for past 6-7 months.
