A 32-year-old man allegedly set his 27-year-old partner ablaze in Nirman Vihar here after the two had an argument over money.

Rohit, a resident of Laxmi Nagar, moved to a temporary slum to live with his girlfriend Sai Ram Ghatia.

Both Rohit and Sai are married but separated from their spouses to live together. The police said on Wednesday night Rohit returned home where he and Sai, who demanded some money to go back to her home in Bihar, had a heated argument. An enraged Rohit then allegedly poured petrol on Sai and set her afire. However, he himself sustained burns. A PCR call was made after which both were rushed to the nearby GTB Hospital where Sai with 90 per cent burns is battling for life while Rohit is reported to be out of danger.
