Delhi Development Authority [DDA] — misbehaviour done by security agencies persons, using motorbike in the park, polluting the park

Address:

BC(West)-82, Shalimar Bagh, Delhi-110088, NEW DELHI, New Delhi, Delhi, 110088

Today I was doing my morning walk at Sheesh Mahal Park of DDA at Shalimar Bagh, Delhi 110088. Many Gunda type persons were moving in the Park. They said that they are removing Cows from the Park, but they were bluntly using Lathis on Cows, which I advised them not to use. But they started shouting and misbehaving with me and other public persons. When I asked them about their department, they said that they are from DDA. When I asked them to provide I Card, they refused. Immediately I lodged a complaint with Police at 100 number.
They were also moving on bike in the car and polluting the Park. I asked the security person, why he has allowed them to enter with Motor Bike, he had no answer.
Though they pretended that they are the officers of DDA, but later on I came to know that they are the security agency person (Gaurav Enterprises).
My question to DDA is:
1. How have they allowed to use Motor Bike in the Park and polluting teh Park?
2. How can they use Lathis so bluntly on teh cows
3. How can they misbehave with general public
Requesting you to take immediate actions. I am also writing to LG on this matter.
Photographs of 2 of such persons sitting on the motor bike without helmet in the Park, alongwith a video are enclosed
