Municipal Corporation Of East Delhi — Neighbour's pet dog is biting everyone

Hello sir/ma'am

Our neighbours have a pet dog who bites everyone.
We have told them so many times about this issue but they always start fighting.
The pet owner name is sagar and their address is 239 patparganj village, mayur vihar ph-1, Delhi 110091

Today his dog has bitten my son. Who is only 4 years old.
It is getting dangerous day by day .

Kindly do some immediate action as soon as possible.

Thanks & Regards
Aashish paarcha
