When she was informed of the bullying incident, Mrs Klein told WHEC this week: 'They didn’t learn any lessons from the other ordeal. I don’t think they ever will.' She also said of the alleged attack: 'Why did you [alleged bullies] do that, what possessed you to be so mean?

She responded: 'I want (the kids) to make sure they never do this again to anybody. I would like them to be kept off the bus for a year, and be forbidden to play any sports, at least for a year.' She added: 'They each try outdo the other. I don’t think they ever picked on the other kids… just me.'
