A day after several stray dogs and birds were found dead in mysterious circumstances in Nizamuddin East, tests confirmed they were poisoned.
According to officials of Friendicoes, the NGO asked to conduct post-mortem on the dead animals, the poison was most probably administered through food.
"The blood and urine samples of a dog have been tested. The cause of their death is poison," said Dr. Prabhakaran, a veterinarian with the NGO. The poison may have been given through food, he said.
NGO officials said 18 dogs and several birds were found poisoned, of which 13 dogs died. Five dogs are recuperating and one of them is critical. The dogs were brought in with symptoms of vomiting and diarrhea.
The bodies of the birds (crows and kites) were found heaped in a dustbin in A-block, Nizamuddin. It is suspected the birds ate the poisoned food and after they died, the MCD sweeper threw their carcasses in the bin.
The first body of a dog was noticed at the Jhoolewala Park on Friday morning by one Rahul Sahni, who called the MCD to get the carcass removed.
Several calls started poured in later, with information about dead or semi-conscious dogs. Residents said that the municipal sweeper removed some dogs on Saturday morning.
Friendicoes officials said that all these animals were sterilized and rabies safe.
A case has been registered at the Nizamuddin police station after residents and animal lovers lodged a complaint.
"We are looking into all aspects. Relevant sections will be added to the FIR after the post-mortem report comes in," said Additional Commissioner of Police (southeast), Virender Singh.
