WATCH: Couple Become Pedophile Hunters to Stop Heinous Crimes

A British couple named Katie and Neil Ivall have gone undercover to hunt down pedophiles and stop them before they can hurt potential victims. The due have set up an entire sting operation by themselves, through which they lure alleged pedophiles and turn them over to authorities.

The Ivalls, who have three children of their own, used Facebook to create a fake profile, posing as a 14-year-old girl named Kerry.

Neil told local news that they set up the profile and leave it up for a few days at a time.

“We were amazed at the number of men that started making contact,” he said. “That was when we realized the extent of the problem.”

They said men would contact the profile, knowing full well she was underage, and try to groom her to become their next victim.

The self-proclaimed ‘Pedophile Hunters’ have already sent two alleged suspects to jail, after the men tried to meet up with the girl from the fake profile. Recently they caught another man, 35-year-old Craig Chapman, in their sting.

Katie said that when messaging the men, she never sets out to trap them. “I won’t push the conversation towards anything sexual,” she said. “At first it might all be entirely innocent.”

She said the men usually turn innocent conversation into flirtatious, and even explicit, advances.

In the case of Chapman, Katie and Neil caught him under the guise of an arranged meeting between Chapman and Kerry. They met him in front of a supermarket, and were able to detain him at that place until authorities arrived.

They were also able to capture the incident on film, which has since gone viral.

Neil and Katie say that they would love to one day train more people to catch more child preditors on their own, although authorities caution that citizens should not take the law into their own hands.
