An Irish tourist died after being attacked by two dogs at an organic farm in Teluk Bahang, about 25km from George Town, Penang.
Both the ears of Maurice Sullivan, 50, were severed and his chin was almost torn off in the attack that took place at about 10am Sunday.
He also had multiple injuries and bites marks on his body.
It is believed that Sullivan had gone to the farm with his 28-year-old Polish girlfriend Agnieszka Jablonska to take pictures of durian trees being planted.
Balik Pulau OCPD Supt Mohd Hatta Mohd Zain said Sullivan's girlfriend had walked away to take photos of the farm when the attack took place.
"Sullivan, who worked as a welfare home caretaker, had came to the farm with his girlfriend to take photos of plants. They planned to upload the photos on the Internet."
"We are still investigating why the dogs attacked Sullivan," he said, adding that the case had been classified as sudden death.
The farm owner, identified only as Teoh, 41, said he had only known Sullivan for less than 24 hours.
"We met at about 11.30am on Saturday and he expressed his intention to learn organic farming."

"He asked me to take him and his friend under a homestay programme so that they can help me out as volunteers during their stay in Penang," he said.
Teoh said his wife was looking out from their house window when she saw two of their four dogs (a male and a female), attacking Sullivan at about 50m from their house.
"My wife saw Sullivan trying to escape but the two dogs chased him, biting his ears, hands and legs. She came out from the house to pull the dogs away but to no avail," he said, adding that his wife also suffered light injuries on her fingers and legs.
Teoh said Sullivan had played with their four dogs on Saturday.
"I am surprised by the attack as we always keep the dogs in the cage after feeding them food every morning. We have been rearing the dogs for two years and there has never been any such incident," he told reporters.
The dogs, both mongrels, were not tied up at that time.
