Neighbours — severe and prolonged overhead leakage of neighbours tank

Address:

New Delhi, Delhi, 110065

I am distressed with serious damages from neighbors kusum talwar, and her sons mohit talwar (Max hospitals) and tarun talwar (Uk).
Their premises in the building appears illegal and only regulated upon consideration. They permit building breakages. High court said i should sue them in 2015, but i sued for police inaction to fir.
They manage iot devices and spyware, are noted breaking in and arranging hostile staff in the building.
Police have been informed of several leakages of their overhead tank since two months, i. E. 13th august 2018
Today they returned and noticed leakages had spread severely.
However, police say they cannot act.
Their broken tank leaks through my lift and staircase walls and spreads on floor.
There is danger of severe collapse of their section.
Police said that they can challan to prevent cholera but did not act.
Also i am with virus and respiratory infection since several days as the staircase is too damp.
I will begin initiatives to cut off wires to their borrowed motor as police have permitted this. The staircase must dry.
A part of their window ceiling has collapsed onto a parked car and smashed the window. They do not prevent further collapse of the ledge.
Police do not know safety or injury prevention. They only act in case of severe damage.
I seek mcd management to impose challan on the neighbour for mismanaging the issue.
The residence is in d2 kalindi colony. 2nd floor. Ashram flyover. Ring road.
