A 41-year-old man and a 39-year-old woman were injured in attacks by one or more wild pigs near the University of Hong Kong on Tuesday.
The man was bitten by a wild pig while he was walking in Mid-Levels on Hong Kong Island, suffering injuries to his face, knees and hands, Apple Daily reported. The woman suffered injuries to her head, chest, arms and legs during a similar attack.
The report did not say whether the two victims were attacked by the same animal.
Both were sent to hospital for medical treatment.
Meanwhile, a taxi driver said he saw a wild pig searching for food in a trash-collection point on Kotewall Road early on Wednesday. That garbage-collection point is about 500 meters from where the animal attacks occurred.
Officers from the Agricultural, Fisheries and Conservation Department (AFCD) and HKU staff patrolled around the area on Wednesday but no wild boar was found.
There have been four cases of wild boars attacking humans in Hong Kong in the past nine years.
The AFCD website says wild pigs are the largest native terrestrial mammal in Hong Kong. Adult boars weigh up to 200 kilograms and can be up to 2 meters long.
In general, wild pigs are secretive and wary of human contact. However, if provoked or threatened they can become aggressive and may attack humans, particularly dominant males or sows with piglets.
