My DS14 was walking to the station after a detention today when a gang of about 8 boys jumped him. They kicked him and one boy even hit him with his belt wrapped around his hand. Luckily, DS was with three friends who pulled them off.
Apparently it all started in school yesterday when one of the boys slapped DS across the back of the head for no reason and there was a bit of a scuffle but a teacher saw it all and stopped it.
I'm going into the school first thing tomorrow and I expect the school to take action.
