BMC — illegal activity, encroachment

Address:

Bhopal, Madhya Pradesh

I live in Veterinary colony at Jahangirabad, their are people who leaves on encroached lands just near our govt colony, now they have started commercial works just near our colony, they have encroached roads from both sides due to which it has gone narrow, we are too annoyed due to the noise of machinery and repairing work, I requested them to not to do their noisy work atleast after evening but its useless, seeking leagal support from authorized authority.
