Delhi Development Authority [DDA] — illegal modification of flat

Address: New Delhi, Delhi, 110019

I am a senior citizen living in the first floor of an apartment complex.
On the ground floor, several walls of the flat have been demolished and are being rebuilt so as to encroach on public space.
This also has the potential to weaken the entire building and reduce my security.
I have made several police complaints and they have come and seen the site.
Urgent action is requested to halt this encroachment and modification
Address of the illegal activity:
Block a - 13, 32 a, kalkaji extension, new delhi 110019
