HYDERABAD, Sept 17: A teenage boy allegedly killed his father, mother and two little sisters at their home in Sarfaraz Colony late on Sunday night for opposing the girl he wanted to marry.

SHO of the Market police station Wahid Bux Leghari told Dawn on Monday that 19-year-old Shahrukh had killed his father Mohammad Akram, 45, mother Shagufta, 40, and two sisters, Insha, 11, and Warisha, 12.

Police arrested the suspected murderer and found a pistol in his possession after the only survivor of the siblings — his younger sister, Zilhash, 18, — decided to speak out this morning after keeping mum throughout the night.

She told police her brother had killed all the four family members because they were opposing his decision to marry a girl living in the same locality.

Shahrukh flew into a rage when the father reprimanded him and killed all those who were siding with him, she said.

The SHO said that when police reached the crime scene Shahrukh tried to deceive them into believing that his paternal uncles Aslam and Jabbar and cousin Danish had killed his family.

He took police to a number of places in search of the purported murderers but police learned later that his uncles were sleeping at their home, said the SHO.

Shahrukh was arrested on Monday morning after initial investigation and a pistol was found in his possession.

The case would be filed formally after burial of bodies.

The deceased Akram was a worker of the Hyderabad Electric Supply Company. He had four children.

The neighbours brought the ill-fated family to Civil Hospital after the tragic incident.

Akram, Shagufta and Insha were pronounced dead on arrival while Warisha died in the morning.
