A 28-year old tourist cab driver was allegedly arrested by Thane rural police on Saturday night for allegedly raping a volunteer at an ashram in Kalyan while she was returning to her house in Ulhasnagar.

The incident had taken place on June 23. The police got to know of clues about the accused after one of his friends told them during interrogation that he had accompanied him to the spot a day after the incident to pick up a wallet which he had forgotten.
