Agra: Concrete illegal structures on the Yamuna flood plains in the Agra region are in line for demolition if the stern warning and notice issued by the National Green Tribunal (NGT) is an indication of the shape of things to come.

The notice, returnable on May 26, came on a public suit filed by D.K. Joshi, an environmentalist and a member of the Supreme Court monitoring committee on environmental issues in the Taj Trapezium Zone.
