Navi Mumbai Police identified a 70-year-old woman, who was killed and her face disfigured by her attacker, with the help of tattoos on her arms and also arrested the accused, a 26-year-old footpath-dweller, an official said on Tuesday.

The woman, a resident of Govandi in Mumbai, was killed near the Vashi bridge earlier this month after she resisted the rape bid by the accused who slit her throat and smashed her head with a stone, he said.
