Mumbai, Dec 10 : Imtiaz Khan, a tailor by profession, used to buy lunch tiffins from a widow Suvarna Surve in Mumbai's Byculla area.
Suvarna's husband had died nearly ten years ago and she was running a lunch tiffin business, which she stopped two years ago after her children began earning money.
On Thursday, Imtiaz came and demanded lunch tiffin, and when Suvarana refused, he slit her throat with a knife.
Police have arrested the killer.
