A Queensland teenager claims he's a "paedophile vigilante", tracking down and catching out men who try to prey on young girls.
The self-styled creep catcher said reading the messages he receives from pedophiles "makes me feel sick".
"Just reading them makes me angry," he told Nine.
"I'm going to catch anyone I can. If you're looking for a young girl, it's probably me."
A video he filmed showing him confronting a would-be pedophile is now in the hands of Queensland Police.
Police have reiterated it is their job to catch sex predators, and vigilantes should not involve themselves.
