Unidentified assailants fired gunshots at the Supreme Court judge's house in two separate incidents.
The JIT, which was formed on Sunday, would be headed by DIG Investigation Sultan Chaudhry to track the unknown suspects who targeted the residence, close to the house of Chief Minister Punjab Shehbaz Sharif, twice over the weekend.
According to police officials, the judge's private security guard, Din Mohammad, discovered a 9mm bullet casing inside the residence at 6am on Sunday after which the police were called in.
He said officers of the Special Branch and Forensic Agency will also be part of the JIT.
As per the preliminary spatial observations by Crime Scene Unit (CSU), the bullet could be stray and on the final stage of its parabolic trajectory fired from a distance, said the report, adding that a search operation has been conducted on the probable direction of the bullet trajectory.
The chief justice is monitoring the situation himself, said a statement issued by the apex court shortly after the attacks. He directed Inspector General of Punjab Police Captain (retd) Arif Nawaz to thoroughly investigate the incident.More news: President Trump's re-election campaign raised $10m so far in 2018
