Two people had reportedly attacked a junior doctor at the hospital for alleged medical negligence that lead to the death of their relative on Wednesday.
Around 250 junior doctors started the strike from Wednesday and demanded immediate arrest of the attackers beside providing them with adequate security.
However, they later decided to resume work from 6 pm after doctors at RG Kar hospital called off their strike.
Patients suffered a lot due to the strike and most of them were referred to other hospitals.
Several operations were also canceled due to the three-day strike.
