Municipal Corporation Of Delhi — stray dog biting case in mayur vihar phase 1 pocket 4 society

Address:

Mayur Vihar phase 1 pocket 4, 110091

I live in mayur vihar phase 1 pocket 4. Yesterday at 11 pm when i was coming to my home 2 dogs chased us from both side of scooty. And they bite me bitterly. This is not the first time when this happend to me, it is a usual thing in my society 10-15 stray dogs are there. Which chases every one who rides two wheeler at night. If proper security guards are there then why we need these dogs.
I want to know why anti dog squad does not take any action against these things.
