A 30-year-old manager of a Pune-based mall was arrested Wednesday for allegedly stalking and defaming a 24-year-old woman on social media after she rejected his marriage proposal, the police said.

The accused Prashant Medhe, a resident of Kothrud in Pune, was arrested on the complaint lodged last year by the victim, a resident of suburban Bandra in Mumbai, an official said. In her complaint, the woman said that someone had uploaded obscene photographs and videos on her Facebook account, along with the contact numbers of her and her friend, he said. Police had registered a case under various sections of the IPC and Information and Technology Act. Police traced Medhe through technical analysis.
