A mum got revenge on her 11-year-old son after he pranked her by pulling her chair away in public - by secretly removing the slats from his bunk bed.

Abigayle Gibbs, 30, was the victim of her son Billy's mischievous antics when he pulled her chair out from underneath her at a family birthday party.

But she got revenge by removing the base of his bed - putting the mattress back - and setting up a camera to catch him taking a tumble.

The stay-at-home mum from Bovingdon said Billy has been pranking her all his life.

She said: "He always jokingly torments me. Sometimes it's an egg on the head, sometimes he puts biscuits in my Red Bull or just makes me jump in the kitchen."

Abigayle said she was 'shocked' when Billy pulled her chair out.

She said: "I didn’t realise what had happened until I was on the floor and my sister started filming.”

She hatched a plan about how to get her son back and made up an excuse when he asked why a camera had been put in his room.

Abigayle recalled; "When he jumped on his bed and fell through I heard him shout 'so that's what the camera was for!'"

Billy has already told his mum that he plans to get her back, and she's "dreading" it.
