A wild pig injured three people in Wong Tai Sin, Hong Kong on Wednesday morning.

At 7am, a 65-year-old female security guard was walking past a public toilet in Fu Shan Estate when she encountered a boar thought to weigh more than 130 kilograms, Apple Daily reported.

The boar ran towards her, making her fall to the ground, after which it bit her right leg, leaving her bleeding.

A man who heard her calls for help tried to beat back the animal using an umbrella, but was also knocked down by the wild boar.

The pig then ran to King Shan Court, 100 meters away from Fu Shan Estate and attacked a 79-year-old man.

The old man was also knocked to the ground and had his leg bitten.

District Councillor Wu Chi-kin, who was walking past at the time, helped call the police as the pig escaped into a nearby hillside.

It was the second case in a week of a wild boar attacking and injuring people. A man was attacked by a boar in Sai Kung, the New Territories on Sunday night.
