Street Dogs — Street dogs attacking and biting

Sir
A lot of Street dogs are ganging up and attacking the residents and our pet dogs
A street dog named Shibu is the most ferocious one and needs to be taken care of. He gangs up and ambushes us while we take our dogs on a walk. A resident gave this dog a blue belt thus confusing whether he is a pet dog or not but when that resident was confronted after at least three attacks by that dog, he clearly stated that Shibu is a street dog he does not own him. Thus I would I request you to please look after this issue ASAP as we fear walking on the streets as he attacks from the bushes which can be fatal too !!!
