Two separate incidents of firing have taken place at the residence of Pakistan's Supreme Court Justice Ijazul Ahsan in Lahore's Model Town, the Dawn reported on Sunday.
The incident took place first on Saturday night and then on Sunday morning.
Post the incident, Pakistan Chief Justice Mian Saqib Nisar visited the residence of Justice Ahsan and ordered a probe.
No casualties have been reported so far.
Justice Ahsan was part of the five-member bench that delivered the verdict in the high-profile Panamagate case last year, which led to the disqualification of Nawaz Sharif, the then prime minister.
Pakistan Tehreek-e-Insaf Chairman Imran Khan took to Twitter to condemn the incident.
"Strongly condemn the firing at Justice Ijaz ul Ahsan's house. These Sicilian-mafia-like tactics to pressurise senior judiciary are unacceptable in any democracy. PTI stands firmly behind the Judiciary & Rule of Law & this is one reason behind our 29th April Minar-i-Pakistan jalsa," PTI chief tweeted.
According to the reports, the judge's house is in close proximity to the residence of the Punjab chief minister Shehbaz Sharif where there is strong police presence throughout the day.
