Mohammad Badal, 32, was brought to DMCH at around 10:00pm on Tuesday with a chest complain.

The emergency medical officer told him to have an Echo Cardio Gram (ECG).

Later he sent Badal to Medicine Ward No 3 as nothing bad was found in the ECG report.

But Badal's relatives claimed that as he continued to complain of chest pain, a doctor pushed him an injection at 11:45pm but there was no relief of pain.

At that time they repeatedly requested the on-duty doctor to see the patient, but he did not respond.

However, the doctor turned up after half an hour and pushed him another injection.

But within five minutes Badal fell unconscious and died, they claimed.

Badal's relatives also alleged that only two junior doctors were on duty on Tuesday night and they could not diagnose the patient's problem.

As the death news reached Badal's residence at nearby Aga Sadek Lane, around 20 locals rushed to the hospital and turned unruly.

At one stage they entered the hospital and assaulted two intern doctors inside a toilet where they took refuge.

They also scolded Dr Ziaus Shams, assistant registrar of Ward No 3.

Panic gripped the inmates during the incident.

A doctor said the patient's condition was very critical and that's why he died despite their best efforts.

DMCH authorities did not make any comment on the issue.
