Parents, famous for their YouTube videos, have lost custody of two of their children after people raised awareness about the potential abuse the children appeared to be receiving.

The YouTube account "DaddyOFive" became increasingly popular over the past few weeks after the parents began playing 'pranks' on their children.

Viewers of the videos raised concerns in the comments about the potential 'abuse' the children appeared to be receiving.

One child, Cody, was accused by the parents for a range of bad behaviour and they then punished him physically and emotionally for it.

The biological mother of nine-year-old Cody and his sister Emma, says she has obtained emergency custody of her children.

"They're doing good," Ms Hall says on the video where she appears with her lawyer.

"They're getting back to their playful selves."

Ms Hall thanked the YouTube community for raising attention towards the channel.

DaddyOFive's creators, which included Cody's father, claimed that the videos were harmless pranks and that the children didn't mind taking part in them.

They have since released a video apologising for what appeared in the videos.

A range of prominent YouTubers said that the videos depicted abuse – pointing to videos where the parents scream and swear at the kids, tell them they are going to be adopted, one of the son's slapping his sister in the face and one where Cody's father appears to push him into a bookcase.

The YouTube channel has received almost 800,000 subscribers and their videos have views at almost two million.

The rest of the videos have now been removed from the channel

The Martins had initially said that the people who opposed the videos were "haters" and that by criticising the stunts they were in fact upsetting the children more.
