Vivek Kumar, a flower vendor at the bus stand here, died last night at a private hospital in nearby Vazhapadi where he was rushed yesterday after he was found unconscious at his father-in-laws' house, police said today.
The deceased and 20-year-old Sasikala, both residents of Vellalagundam village near here, got married four months back.
Since Kumar's parents opposed their marriage, the couple were staying with the girl's family, who belonged to Vanniyar community.
Police said a case under CrPC section 174 (unnatural death) had been registered and investigations were on.
Kumar's death comes close on the heels of the death of Dalit youth, Illavarasan, in neighbouring Dharmapuri district in a tragic end to an inter-caste marriage that triggered anti-Dalit violence last year.
Illavarasan was found dead on July 4 along a railway track a day after his wife, a Vanniyar girl, said she would live with her mother.
