A group of teen bullies got a taste of vigilante justice after they were filmed beating up a young disabled woman in Hawaii.

Four teenagers - aged 13, 14, 16 and 18 - were arrested after horrific footage showed them surrounding and assaulting the confused woman, 21, who tried to shield herself as she was kicked and punched in the head.

The victim, named only as Carly, remained crouched on the ground and did not fight back as the attackers take turns assaulting her, with local spokesman Michael Kitchens branding their behavior 'evil.'

The brutal April attack was posted online earlier this month and sparked widespread anger from the Wahiawa community, who took matters into their own hands and hunted down the suspects.

The community members livestreamed themselves as they went looking for the bullies at their homes, with as many as 11,000 people watching at one point, as reported by Hawaii News Now.
