A man turned himself in to police yesterday saying he was responsible for setting fire to a dog in its kennel in a Tuen Mun village at the weekend.
The computer technician, 31, told police he was so annoyed by the animal's barking that he poured paint thinner over the kennel and set it alight.
The owner put out the flames but the dog was so badly burned it had to be put down.
The attacker lives in a high-rise block of flats next to the village house in Kei Lun Wai where the owner kept his dog on the forecourt.
Identified only as Mok, the technician was arrested for cruelty to an animal. He was granted bail and ordered to report back to police on September 25.
The mongrel bitch was set alight about 7pm on Saturday. Officers from the Society for the Prevention of Cruelty to Animals (SPCA) took it away but it could not be saved.
"She suffered severe burns and was put down to end her suffering," a spokeswoman said.
"It is possible Mok surrendered because of a guilty conscience," a police officer said.
Under the Prevention of Cruelty to Animals Ordinance, the maximum penalty for animal cruelty is three years in jail and a HK$200,000 fine.
