Two land mafias, who sold flood-prone land along the Hindon river fraudulently showing it as residential space, were Friday booked under the stringent Uttar Pradesh Gangsters Act, the Gautam Buddh Nagar administration said.

They have been identified as Devendra Yadav and Satyendra Yadav, who live in Chipiyana Khurd Thori area of Greater Noida, the administration said. "Both of the persons have duped several people of their money by selling them flood-prone land along the Hindon river by fraudulently showing it as residential land. By doing this, they also obstructed the natural flow of the river," the administration said in a statement.
