Stray dogs are killing children in India. Scientists want to find out why.

NEW DELHI — A team of scientists in India is investigating why packs of stray dogs in villages near the north Indian town of Sitapur have mysteriously started killing children.

In just a week, six children between 5 and 12 years old were killed by strays while more than two dozen other children have been injured in attacks.

The attacks have terrorized the town. According to local reports, school attendance has dropped and residents say they believe the killer beasts are hyenas, not dogs. Vigilante dog-catching squads have started shooting and strangling animals, while local authorities have recruited police officers, municipal workers and a team of expert monkey catchers to apprehend the strays.

The World Wildlife Fund and the Indian Veterinary Research Institute have sent teams to figure out what has turned the dogs into child killers.

“We’re here to find out how and why did the dogs turn violent and started attacking people,” Dr. Dinesh Chandra, from the Indian Veterinary Research Institute, told the ANI news agency.

Feral dogs are a common sight in India, though attitudes toward them vary. Some communities feed strays and take them to vets, while in many places dogs are beaten and chased away.

Sabir Ali, whose 10-year-old nephew Kasim died in a dog attack, said that the killer dogs were not ordinary strays. “In shape and size, the dogs that attacked my nephew were different from normal street dogs,” he told the Indian Express.

One of the recent deaths was of a 7-year-old girl named Gita, who had gone to the field to pick mangoes.

“They were biting the girl on her neck, thighs and stomach,” local resident Ram Kripal told the Indian Express.

“They were even eating the meat while she was still alive. I am sure if we had reached five to 10 minutes later, we would not have even found the body,” he said.
