At least 30 people in West Bengal, India, beat up a doctor and ransacked a hospital after a patient died, the Calcutta News reported.

The attackers alleged that 52-year-old Kajem Sheikh died because of Dr. Santanu Mondal’s negligence, a senior police officer from the Nabagram police station told the newspaper.

Sheikh was admitted to a hospital in the Nabagram village of the Murshidabad district Sunday night with severe stomach pains.

“Since it was Sunday, after hurriedly examining Kajem, Mondal scribbled a prescription and left for his quarters, which were on hospital premises,” the police officer said. “Around 8:30 p.m., Kajem’s stomach started to swell. But when his relatives called for the doctor, Mondal refused to come, saying it was not his duty hours.”

Sheikh was then transferred to nearby Beharampur General Hospital, but he died on his way there. That is when friends and relatives of the man broke into Mondal’s house and attacked him. They later ransacked the hospital.

The police officer said no arrests have made yet.
