Police have arrested a 40-year-old physiotherapist here for allegedly raping a 16-year-old physically challenged girl at his clinic in suburban Santacruz, an official said on Wednesday. The accused, who was nabbed on Thursday, had allegedly been sexually assaulting the girl, suffering from speech impairment and other physical disabilities, for more than a year whenever she used to visit his clinic, the police official said.

The crime came to light on Tuesday when the girl sent a text message from her mobile phone to her parents, informing them about the offence. Her shocked parents filed a police complaint on Thursday and the girl also revealed details of the offence to police, the official said.
