Five people have been arrested in connection with the killing of a PMK functionary near here, police said Thursday.
Ramalingam was allegedly done to death on Tuesday after he questioned some people about religious conversion in the area, they said.
BJP national secretary H Raja visited Ramalingam's house and consoled the family members.
PMK founder S Ramadoss sought constitution of a Special Investigation Team to probe the case, besides seeking financial compensation to the bereaved family from the central and state governments.
"Ramalingam was killed the next day he prevented religious conversion.. the culprits should be punished," she tweeted.
