An Ohio father has provoked controversy by posting a video of himself forcing his daughter to walk several kilometres to school as punishment for being a bully.
Matt Cox forced his 10-year-old daughter Kirsten to walk 8 kilometres to school on a cold day while he followed behind her in his car.

He said in the video the temperature dropped to 2DegC as Kirsten walked.
"Bullying is unacceptable," Mr Cox said from inside the car. "This is my small way of trying to stop it in my household."
He later told ABC news his daughter had received a three day suspension from using the school bus service due to allegedly bullying other children.
"Parents need to hold their kids accountable. That was me showing how I hold my kid accountable," he told ABC.
"I'm not going to be another parent that's just going to brush things under the rug and say kids will be kids."
The video on Facebook has received more than 16 million views and 69,000 comments, not all in favour of Mr Cox's actions.
"He's bullying his kid on social media for bullying others on a school bus. While punishing a kid is appropriate, embarrassing her publicly is just cruel. And he wonders why his kid is a bully," one person wrote.
"This kid is probably going to need therapy after this. How is she ever going to be able to trust her father again? He humiliated her on Facebook, just so he can get a bunch of likes," another said.
But others said Kirsten needed some tough love to set her straight.
"We need more parents like you," one person said.
"Way to go I wish more parents were like you," another wrote.
