A bit long, sorry...
Ds started reception a few weeks ago. He is a very large, loud, confident child although not very good at relationships with other children (too bossy).
He is only doing afternoons at the moment and last week dh arrived to drop him off at school early. To pass the time ds and dh were picking blackberries down a path beside the playground. There were 2 older boys (about 7) in the playground and ds asked if they wanted some and was giving them to them over the fence. One of them was laughing at ds and throwing them on the ground and stamping on them. Ds then kept giving them to one boy but refused to give them to the other (who I shall refer to as Thug - I know its not nice, but wait and see why). Thug was still laughing at ds and suggested that he climb the fence into the playground and go with them. Dh did not think that this sounded like a friendly invitation and took ds away. Dh said at the time Thug's invitation actually scared him (dh not prone to worry and we had never met this child before).
A week later and yesterday was the first day ds was in the big playground (reception have their own). Thug got him with another friend and dragged him to a quite cornner and would not let him go while they pretended to shave his head with a stone. Ds shouted for help but no one could hear him. He got away and they chased him and dragged him behind a kind of tent thing they have and did the same thing again until finally ds got away and ran inside. I should say to be fair that they did not actually hurt ds.
Ds told dh who told the school and the school are investigating it.
I must confess, I don't really know what to do. I have the feeling that Thug waited a week for ds and will wait for him again. The way they treated him seems to go beyond normal childish aggression and be more spiteful than that. Had they just pushed him a bit I'm not sure I would be worried, but it seems more than that to me.
The school know who Thug is and are apparently going to confront him about it today (and I'm sure he will deny anything happened). I worry that this may make things worse.
Am I right to be concerned and what should I do?
