Delhi has an anti corruption helpline 011-27357169. You can call the helpline and seek assistance in conducting sting operations on corrupt officials and that will act as supportive evidence against the officer in the dock who after the sting is recorded will be entrapped by Delhi’s Anti Corruption Department and caught red handed receiving the bribe. The Chief Minister says it will act as a deterrent against corruption by instilling fear in corrupt officers. But the sting method is raising some eyebrows too.
