Junior doctors at Nil Ratan Sircar (NRS) Medical College and Hospital in Kolkata went on strike on Tuesday after one of their colleagues was allegedly attacked by the family of a patient who died on Monday.

The junior doctors locked up the hospital gates, stopped work at the outpatient department (OPD) and sat on a dharna to protest against the attack. However, patients later broke open the gates to enter the hospital.

Adequate security has been deployed in the wake of the incident.

Shubham Roy, a student at NRS Medical College in a Facebook post, said that the intern doctor, Paribaha Mukhopadhyay, was critical and had a skull fracture due to the beating.

He further slammed the government for not providing security to the doctors in medical colleges.

Earlier, the family members of the deceased patient, Mohammad Shahid (75), had staged a protest alleging medical negligence on behalf of the doctor.

The junior doctors took out protest marches throughout the city and mobbed two ministers, Chandrima Bhattacharya and Nirmal Majhi.

Health Minister Chandrima Bhattacharya said four people have been arrested in connection with the case.

"Emergency is open and talks are on. Four people have been arrested in connection with attack on doctors," Chandrima Bhattacharya said.

Following the arrest, the junior doctors lifted the demonstration but said that they would not report to OPD tomorrow as a mark of protest.

The outpatient department (OPD) facilities of government hospitals and private hospitals in West Bengal will be shut from 9 am to 10 pm tomorrow. The Emergency section, however, will remain open.

Meanwhile, BJP leader Mukul Roy blamed the Trinamool Congress government for not taking prompt action as the patient's kin belonged to a particular community.

"The attack was carried out by Trinamool Congress men," he said.
