Patna, Feb 21 (IANS): A man stabbed a married woman in a busy market area here following which the woman, who was his girlfriend, snatched the knife from him and stabbed him back. Both have died, police said Saturday.

Chanda Devi, mother of two children, was in her early 30s. She died because of her injuries Saturday, a day after she was stabbed by Dheeraj Kumar, 25, who was unmarried. He died of his injuries late Friday.

After battling for life for more than 10 hours, the woman died at the Patna Medical College and Hospital where she was admitted for treatment, Deputy Superintendent of Police (town) Vivekanand said.

"Dheeraj Kumar along with the woman fell to the ground and both were rushed to the hospital where he died during treatment," he said.

Patna Senior Superintendent of Police Jitendra Rana said that a preliminary probe suggests the shocking incident was related to an affair between them.

Police said Dheeraj Kumar, who used to work as a salesman in a garment shop, stabbed Chanda Devi as he was angry that she was going to have an affair with another man despite her assurances that she won't cheat on him.

Police have recovered the knife as well as their mobile phones from the site of the incident.
