Mexico City investigates reports of dog poisoning at park

A popular dog run in a picturesque Mexico City park remains closed following reported cases of dog poisoning.

Orange tape surrounded the fenced in dog area of Parque México in the wealthy Condesa neighborhood Tuesday. Large banners hung on the fence warned of a "Red Alert" for the poisoning of dogs.

Smaller paper signs posted throughout the park by the local government advised dog owners to keep their pets on leashes while an investigation into the poisoning continued.

Several police officers standing outside the dog run said they did not know when it would reopen. One sign posted by a Facebook group on the dog run gate had photos of nine dogs it said had been poisoned since Sept. 29, but the government has not offered an official figure.
