Two parents, who took matters into their own hands against a man they say was propositioning their 13-year-old daughter, may now be charged with assault after apparently restraining that man with zip ties when he turned up at their Canada home.

The unnamed parents in Port Alberti, British Columbia, said the 28-year-old man showed up at their home Thursday, expecting to have sex with their teenaged daughter, CTV News reported.

The girl's parents then allegedly tied up the man and called police; the couple also apparently filmed a Facebook Live video of the restrained man, with the woman calling him a "predator" and saying police refused to go to the house for the "meeting."

"He came to my house to meet my 13-year-old f-----g daughter to f--k her. We f-----g tackled him and zap-strapped him and called the police," a female voice could be heard in the video.

"Because earlier today when I asked the police to come here for this meeting, they said no," the voice continued. "...Why wouldn't the police come and help me catch this predator that just came to my f------g house?"

Canadian police confirmed parts of the account, telling news outlets that they responded to a disturbance that left a man tied up as "a result of vigilante actions." The man was then freed of his restraints and taken to the hospital by police, and has not been charged.

The parents were arrested at their home.

Police later stated the couple could face charges for assault resulting in bodily harm and forcible confinement, according to CHEK News.

The parents defended their actions against the man, saying they discovered the 28-year-old was sending her daughter "explicit messages" via Instagram over a month ago. The mother told news outlets that they told the police about the messages but were told to block the man's account and forget about it.

"They wouldn't even look at my phone," the mother told CTV News. "I've been waiting for six weeks for the police to give me a name behind the Instagram account."

The mother then said she messaged the man as her daughter, inviting him over to their home. When she asked police to be there, she said they refused. When the man, who is an apparent acquaintance to the family, showed up, that's when the couple allegedly assaulted him.

A corporal with the Port Alberni Royal Canadian Mounted Police said the man has been under investigation for child luring since March, and slammed the couple's "vigilante actions" in an issued statement.

"Police want to stress that at no time should the public take the law into their own hands," said Cpl. Amelia Hayden.

"These are serious matters and the police are investigating and taking appropriate steps to address the original complaint filed in March. Vigilante actions like these are not only illegal and put people in danger, but they also have the potential to compromise the original ongoing investigation."

Hayden said the mother was also told not to pursue the meeting, but went forward with it anyways.

In an interview, the father called the charges "ridiculous."

"Shouldn't a guy be able to protect his own family in his house? This is ridiculous, and I felt that was the best way to do it."

The mother added: "If I get charged, I still feel it was the right thing."
