Hundreds of lawyers stormed and ransacked a key hospital in Lahore on Wednesday to avenge what they said an assault by doctors there on a fellow advocate a few days back, and at least three heart patients died during the violence, authorities said.Lahore city police chief Zulfikar Hameed said the mob smashed windowpanes, doors and equipment at the Punjab Institute of Cardiology and also set several vehicles on fire. Some of the protesters fired gunshots and pelted arriving police with stones and bricks, according to a hospital doctor, Ashraf Nizami. Several lawyers were arrested, police said. “It was catastrophic for hours,” Nizami said, adding that a 70-year-old female patient was among those dead, and several patients were left unattended for hours, during the violence. He said the attackers forced doctors and nurses to flee, leaving patients in emergency and intensive care unattended. Police fired tear gas to quell the mob while terrified patients and hospital staff fled to safety, officials said.Lahore government official Kamran Ali said the lawyers were enraged over what they said was the beating by doctors of a lawyer at the hospital over his refusal to get in a queue of patients. He said the lawyers were particularly angry about the doctors disseminating a mobile phone video on social media showing the beating. Videos of the incident shared on Twitter showed police officials, clad in riot gear, rendered helpless as a swarm of lawyers, outnumbering the law enforcement personnel, broke the entrance of the hospital.Grand Health Alliance Chairman Dr Salman Haseeb had earlier put the death toll at four. However, Punjab Health Minister Yasmeen Rashid at a press conference later in the day confirmed the death of three people. “One woman was being resuscitated, one patient was admitted to the CCU 3 ward and one was in the emergency ward since Tuesday and had been quite stable but got a cardiac arrest,” the minister said.

The president and secretary of the Lahore High Court Bar Association also arrived at the PIC to convince the angry lawyers to leave the hospital.Prime Minister Imran Khan summoned an emergency meeting in the wake of the attack. According to reports, the prime minister contacted Punjab chief secretary and inspector general of police, summoning a report on the incident within an hour.“We will not let anyone take law into their hands,” the prime minister was quoted as saying.
