Depressed over their only daughter eloping with a man outside their community, an elderly couple allegedly committed suicide at their home in Tamil Nadu's Pollachi, around 35 km away from Coimbatore on Sunday.
The couple had advised their 24-year-old daughter, who had fallen in love with the man while in college, not to continue the affair, police said.
However, the daughter left home last evening, telling her parents that she was going to live with him, they said.
Upset over her decision, her mother called a woman relative last night and told her that both she and her husband were going to commit suicide by consuming insecticide.
The woman who rushed to the home with some relatives, found the couple lying unconscious on the floor and they were immediately rushed to the government hospital in the town.
However, both husband and wife died en-route to the hospital, police said.
The relatives could not contact the daughter as her cell phone was switched off, they said.
