The Delhi police arrested the creator of the ‘Bulli Bai’ app from Assam on Thursday, just days after their counterparts in Mumbai apprehended three other accused in the case. The app, hosted on GitHub, was used to target prominent Muslim women, by listing their names and photos for auction.

The Intelligence Fusion and Strategic Ops (IFSO) unit of Delhi police’s special cell picked up Niraj Bishnoi, 20, from his house in Jorhat district of Assam. Sources said Mumbai police were just an hour away when he was taken into custody. “The main conspirator and creator of the Bulli Bai app on GitHub and the holder of the Bulli Bai Twitter account has been arrested from Assam,” said KPS Malhotra, DCP special cell, Delhi police.
