About 40 interns at DMCH went on strike Wednesday night after one of their colleagues was assaulted by outsiders.

Hospital sources said seven patients died and at least 300 others left the hospital during the strike.

After the strike was withdrawn, DMCH Superintendent and Dinajpur Civil Surgeon Dr. Azizur Rhaman filed a case with local police station in connection with the assault of an intern doctor. But none was named as accused. None was arrested.

The interns' demands include arrest and punishment of the attackers.

On the night of June 26, relatives of a patient had hot exchange of words with intern doctor Dipankar Chakravarti at the hospital centring examination of the patient.

On the following evening, when Dipankar was going out of the hospital, he was beaten by relatives of the patient, triggering a strike by all interns.
