On the eve of her birthday, a 24-year-old software engineer in Tamil Nadu was chained, cut and burnt alive by her classmate who had undergone a sex change operation to marry her, police said. 

The disturbing incident unfolded in Thalambur near Kelambakkam, a quiet southern suburb of Chennai. According to police reports, 26-year-old Vetrimaran alias Pandiya Maheswari, under the guise of a birthday surprise, blindfolded 24-year-old R Nandhini and subjected her to an unimaginable ordeal involving chains and petrol.

The unsuspecting victim, a native of Madurai and a software engineer, had been residing with relatives in Chennai. Vetrimaran, having changed his name from Pandiya Maheswari, lured Nandhini into this deadly trap on the pretext of a birthday celebration.
