The Commission took suo motu cognisance of media reports alleging honour killing of a young Dalit man, who married a girl of upper caste, in Udumalaipett in Tirupur district on March 13, said an NHRC statement.
Three unidentified men attacked the couple -- Shankar and Kousalya -- with sickles. The man died on the way to Coimbatore Medical College Hospital, while the woman is undergoing medical treatment.
"The incident raises serious question relating to the safety of persons belonging to lower castes. In this case, the man belonged to a Scheduled Caste and had married an upper caste Hindu girl.
Twenty-two-year-old Shankar had married Kousalya against the wishes of the girl's family in 2015.
