The court has warned that if the brother of Shahzad Akbar, a former aide to the PTI leader, is not brought before it, Shehbaz Sharif, the prime minister, will be summoned.
Justice Mohsin Akhtar Kayani gave the warning on Friday while deciding on a petition seeking the release of Murad Akbar, who was reportedly kidnapped by law enforcement personnel.
The court ordered the capital police to hand over Murad within two days on May 31.
