Supertech — Black dog attacking and biting children and puppies

I am a resident of Supertech Ecociti sector 137, there is a black dog staying near the central park kids playing area. He has bitten more than 20-30 children from our society and even my child. We have made several complaints to the society to get that dog removed from the society. Today also he has attacked me and my puppy in broad daylight, with atleast 10-15 people trying to scare him away. If you find out in this society many many people have complaint against that one dog, there are dog lovers here who are only fighting and not ready to adopt him and take him home. The society security is doing nothing about it. It is a major security concern as a resident of this society. Are they waiting for someone to die of dog bites to take an action regarding this. Many people have faced the casualties of this dog. We want a strict action against the society security management as this is a major security concern. We are scared of living here or taking our kids and puppies out of the house.
