Dr Vipul Chaudhari was arrested for filming a colleague while she bathed in the hostel.A day after a resident doctor at Sion hospital had been booked for filming a female colleague while she bathed in the institution’s hostel, the hospital authorities promised structural changes in the bathroom to ensure such incident wasn’t repeated. “There is a gap of around one ft between the bathroom wall and the ceiling, and we will make sure it is filled,” a senior official from the hospital said, adding an internal inquiry has been launched.The woman, who lives in the resident medical officers’ quarters, has alleged that the accused, 26-year-old Vipul Chaudhari, also took pictures of her the entire time that she was in the bathroom.According to investigators, Chaudhari filmed the woman from an adjacent shower stall around 5 pm, and she caught him in the act as she emerged from the bathroom.The Sion police, which booked Chaudhari under Section 354 of the Indian Penal Code for infringing on the woman's privacy and under Section 66 of the IT Act, said the accused’s mobile phone has been sent for forensic tests.“There is enough evidence against him. We are investigating whether this is his first such offence,” Senior Inspector B Z Gavit said. Chaudhari is from Jalgaon, and holds a post-doctoral degree from KEM Hospital.Dr Suleman Merchant from the Sion Hospital said, “The matter is being investigated by an internal committee that deals with sexual harassment.”
