Age 10, been to more schools than his age before coming to my school. First couple of weeks he was quiet, then aspects of his behaviour began to surface. For example, a couple of pupils playing a board game, he walked past, his hand came out and quickly shoved the board dislodging the pieces. Walked away laughing. Took another pupil's toy and broke it (in front of teacher), then denied doing it. When in another classroom, damaged a card belonging to a pupil. Admitted it to a few pupils(laughing) but denied it to teacher. Upended a board game so all the pieces went on the floor, laughed, and blamed another pupil. I witnessed this. He denied doing it again and again. Myself and teacher have been keeping a note about incidents we witness or hear about to build up a picture. I get a sense that he simply feels an urge to damage things, spoil games, cause a scene, and suddenly the hand snakes out BAM, game spoiled, toy damaged or whatever. It is the barefaced denial when clearly seen doing this that is odd. Worryingly, I forsee that this is just the beginning of more disturbing behaviour to come. He displays a cynical attitude towards teachers and the school saying he hates school/teachers and doesn't see why he has to attend. Any advice would be appreciated.
