Delhi Development Authority [DDA] — I am complaining about a DDA Park

I am a resident of Dwarka Sector 3, Matiala and have a DDA park near by my house in which we go for walk and exercise everyday but a gentleman from the society located opposite of the park has asked the security guard to lock the gate and not letting anybody enter since last few days. He even used harsh tone while arguing with us about the same matter. As it’s a public property (under DDA) and open for general public plus do not require any permission to enter. So I request you to look into this matter asap and I hope I can have a resolution without going to further authorities.

Thank you
