"The authorities have opened a parallel emergency system where senior doctors will exam serious medical cases of the patients," sources at the North Bengal Medical College and Hospital told ANI.
There are 22 OPD doors in these hospitals where more than 4000 people turn up every day on an average, the source added.
"We have already explained our demands in posters. The Chief Minister should come here and she hasn't reached yet," a doctor, who was protesting here, said.
Moreover, the incident has triggered protests from doctors in other government hospitals across the state.
According to hospital authorities, adequate security arrangements have been made in the premises of the hospital.
Earlier, the family members of the deceased patient staged a protest alleging medical negligence by doctors.
West Bengal Health Minister Chandrima Bhattacharya said four persons have been arrested in connection with the case.
The doctor who was attacked is reportedly admitted in the intensive care unit after he sustained grievous injuries.
