The toll in the Tung Chung dog poison case is now 11 following the deaths of five more pets.

In the latest incident, an 80-year-old resident of San Tau, where six dogs died in the early hours of Saturday, called police at 8am Sunday morning after two of his dogs fell ill.

A female dog died at the scene and the other was sent to the SPCA.  The second dog, a male, died this morning, SPCA told Lantau News.

Three more dogs died at the Tung Chung Animal Clinic on Saturday, all of whom had been near the Hau Wong Temple, about three kilometres east of San Tau.

Local residents have said they found meat balls suspected of being mixed with poison near the temple and had shared photos via social media, Apple Daily reported.

The head of the pet clinic said that at about 11am on Saturday a dog owner brought in two pets he had been walking at the Hau Wong Temple. Both were vomiting and were suspected of being poisoned.

One died shortly after reaching the clinic, while the other stabilised after receiving an injection. However, after the effects of that wore off at around 6 pm it began convulsing again. The owner, not wanting to see it suffer further, agreed to let it be euthanised.

At 4pm another dog was brought to the clinic which had also been walked near the Hau Wong Temple. The owner said she had seen the dog eating something on the side of the road. After she returned home, it began to convulse and died only a few minutes later.

The AFCD is conducting post-mortems on the deceased animals.

Police arrested a San Tau man on Saturday morning on suspected criminal damage after he allegedly slashed his neighbours’ bike tyres following the sudden deaths of six of his dogs. Lantau North police are investigating.
