The incident came to light yesterday when the carcass of the dog was spotted by some residents of Surya Niketan, who used to feed the animal. They called the Police Control Room (PCR) and informed an NGO, which deals with cases of animal rights, about the incident.
It was only after the residents created a ruckus over the incident that an FIR was lodged at the Anand Vihar police station under the Prevention of Cruelty to Animals Act, section 429 (Mischief by killing or maiming cattle, punishable with a maximum jail term of five years) and section 120B (criminal conspiracy) of the IPC.
They claimed that the members of the family did not like the dog's presence in the area and had problems with the animal sleeping under their car, he added.
The dog's head was found crushed and the locals alleged that the animal could have been "intentionally" run over by a vehicle.
One of them alleged that while they gathered around the carcass, one of the members of the family which had problems with the dog, asked them to keep quiet. They even expressed happiness at the animal's death, the officer said, quoting from the complaint given by Rahul Kapoor, a resident of the area.
