A man accused of raping and torturing a 12-year-old girl in her Delhi house has been arrested, the police said. The survivor underwent a surgery at AIIMS hospital and was critical, Chief Minister Arvind Kejriwal said earlier today, calling it a barbaric crime. The survivor was sexually assaulted at her west Delhi house on Tuesday, when her parents were at work. She was repeatedly hit by a sharp object on her head and face and was lying in a pool of blood when her neighbours found her and informed her parents, the police said.
