Municipal Corporation Of East Delhi — Construction without approvals

Respected Sir,
I want to inform you about the unauthorised construction that is currently active at the address block B2 h.no.30A yamuna vihar Delhi -110053 at front and back side of the house.
This is an authorized government colony where as per construction laws building plans have to be passed by competent authority before taking any construction work.
Attached are photographic evidences.
We also submitted the complaint application regarding the same subject by visiting at the MCD office Shahdara but no action has been taken.
We have also attached the copy of application submitted at MCD office. Also this building was constructed during 1980s without any pillars so such illegal construction is grave danger to our lives.
Request you to take kindly appropriate action at earliest.
