Mumbai: Two persons today allegedly assaulted a senior doctor at the KEM hospital in Parel to protest the hospital's action of marking numbers on the bodies of the Elphinstone station stampede victims, police said.

The incident occurred this evening when the duo, believed to be Shiv Sena workers, assaulted the forensic science head of the KEM hospital, a senior police official said.
