He added that the relatives of the female patient had not intended to cause the deaths but the situation worsened due to the violence.

Maaz told Dawn that while the chaos was taking place, Noorul was feeling unwell and was left unattended for nearly an hour.

"When they (hospital staff) noted this, they attempted to resuscitate him but were unable to successfully to do so," he added.
