Three students were caught with mobile phones that had copies of the leaked paper at a center at Bhiwandi in Thane district on Wednesday. This was after an NGO complained about similar incidents on March 11, 13, 15 and 18. Bhiwandi police have filed a FIR on both incidents and investigations are going on. Govind Sharma, founder of Samvad foundation whose complaint had prompted the board to register a complaint said that the history paper which was scheduled at 11am on Thursday was also out on social media minutes before the exam. "We received images of the paper from 10:10am. We have informed the police and the board officials about the same and have shared images of the same with them," added Sharma. Following his complaint, flying squads of the board were deployed. They found three female students entering an exam centre with their phones at Bhiwandi.
