MUMBAI: Suspecting his friend of having stolen his wallet, a 27-year-old man allegedly raped the friend’s 90-year-old grandmother in a drunken stupor at her home in a chawl in Chembur on Friday. The woman, who is visually challenged, has been admitted to a hospital, said the police, adding that her condition is stable.

The accused Prabhu Nadar gagged and trussed up the woman, who was asleep, before raping her repeatedly. He was arrested the same day. The woman stays with her grandson who is a labourer.

In her police complaint, she has said that the door to her house had been kept slightly ajar due to the sweltering heat. “I tried to fight him but he overpowered me. When I tried to scream, he gagged me and tied me up,” states the complaint.

The survivor, who tried for at least four hours to wriggle free, managed to call out to her sons who live in adjacent houses. Senior inspector Bhagwat Sonawane of Tilak Nagar police station said she has sustained injuries and swelling on the private parts.

A police officer said that the blind woman was unable to give a description of the accused. “But she told us that the man was reeking of alcohol. We learnt that a few men in the locality had had a drinking binge the previous night. Our inquiries led us to Nadar who confessed to the crime,” said this officer, adding that Nadar had dozed off by the roadside near the chawl.

Deputy commissioner of police Sangramsinh Nishandar said Nadar has been booked for rape. He has been sent to custody.
