On completing 50 days in power, the Delhi government - led by Aam Aadmi Party chief Arvind Kejriwal - launched its anti-corruption helpline, 1031. The helpline, advertised through billboards and radio spots, urged people to make audio or video recordings of anyone - be it government officials or the police - demanding bribes. Now, it appears that several police stations in Delhi have banned visitors from entering the station premises with cell phones. The Ghazipur police station in the eastern periphery of Delhi, for instance, has put up a notice with a list of items that cannot be taken inside, which includes, you guessed it, cell phones with cameras. At some other police stations, officers were seen frisking visitors or asking them to leave their camera phones outside.
