On Saturday, the victim, Ravinder, saw a couple of men urinating outside the metro station and objected to it, police said.
Enraged, they came back in the evening and thrashed him. Ravinder called up his family members who rushed him to a hospital where he succumbed. A case has been registered and teams have been formed to nab the accused.
Police are trying to find CCTV footage from the area to identify the accused.
