Delhi Development Authority [DDA] — illegal encroachment on market terrace

Address: 110019

I am the resident of chittaranjan park a block.
I could see the illegal encroachment had been done on market no 3, cr park terrace by the shop owners.
All the servant rooms and kitchen had been build and at night drinking and shouting of the staff is non stop.
Once should take the appropiate action and lay down the illegal contrcution being made by the shopowners.
