Bruhat Bengaluru Mahanagara Palike [BBMP] — Illegal construction and encroachment near my building

Address:

67, 3rd Main Unity Encalve Gedalalahalli

Hello sir/Mam

Mr Nya and Mrs Afnan from site no 68, Unity Enclave, Gedalahalli(Behind Mantri splendor) had dug my boundary and building footing due to which my drainage broke and complete building was in danger. They did not left any setback and due to which my whole ventilation will go off.
On complaint to BBMP(Horamamvu), work was stopped by officials.
But they resumed work today and on asking they are telling they got called to BBMP frm some high status guy after which they were allowed to resume work.
I dont understand how BBMP can allow violation of rules .
Please look into this matter.
