Dr Siddique, the owner of Iqra Medical Complex in Johar Town, was shot and killed last week as he was leaving a mosque in the city’s Valencia Town area after Friday prayers. He succumbed to his injuries on the way to the hospital.

According to police, the deceased’s son, Qayyum, has admitted to hiring hitmen to assassinate his father.

The police officials said Qayyum ordered the hit because his father was not allowing him to marry a certain girl. They also revealed that Qayyum had attempted to kill Dr Siddique six months ago, referring to a previous case the deceased had filed with the local Chung police station.

Police registered a case against four unidentified attackers and began an investigation.
