Mr Caleb who happens to be a school teacher hit his class student Sam.
Here’s the backstory; the whole class was making fun of Mr Caleb while he was give class lectures, Sam was the lead noise maker.
Mr Caleb to a piece of paper and threw it at Sam who picked it up and threw it back at him. This made the whole class to start laugh and Mr Caleb was finding funny.
After a few exchanges of pieces of paper, Mr Caleb walks over to Sam grabs him and knocks him out in front of the whole class.
This is very unprofessional for a class teacher, I hope Sam’s family press charges
