Delhi Development Authority [DDA] — Parking in Freeway

Hi, I am from Pocket - D, Mayur Vihar 2, Delhi - 91.
People are parking their vehicles in freeway area which is blocking the movement of people/ small vehicles.
One such incident is freeway/ path next to Flat no. 13, Pocket - D. Ground floor resident in front of Flat no. 13 has started parking his car in freeway which is creating problem for other residents and blocking movement.
When asked to remove the vehicle, person did not agree and even threatened us. Requesting to look into the matter.
Thanks.
