Some more info - based on the replies.
- There are no pics, this thread isn't useless without them.
- This is in Thailand, it's a private school, so there's no deabeat dad - I presume they are doing ok financially as it's not cheap
- The earlier incident, where he pulled on her bra strap - he also teased her about her periods - and I don't take kindly to disrepect
- Thailand is not a litigious society, so there's no real mileage in a court case looking for a payout
But the questions about the parents are really bang on. I don't know them OR know enough to know it's being dealt with properly by them. On the one hand, it's easy to blame the parents for a bad kid. Plenty of wealthy kids turn out to be brats. On the other hand, the parents could be normal and be horrified by this. I would presume that the mother would be horrified at being dragged into school and told their kid is a sex case. Even more when word gets around. But I don't KNOW this. I would also presume that having the kid suspended is a major inconvenience for them - but for all I know, they might just have laughed it off and gotten the maid to look after him during his suspension.
So I have told the school that I am weighing up my options - which are to pull my daughter from the school and to involve the police. What I have suggested to de-escalate things is a sit-down with the boy's parents at the school - so I can get a feel for how seriously they are taking this. If they are good people and he's been properly punished AND they are getting the kid professional help - I'll leave it at that.
