A teenage boy posted videos of students in uniform 'sparring' in a carpark on his blog. He had apparently filmed the one-on-one fights himself.

The teenager had earlier also called his teacher a dog on his blog and fashioned a crude tombstone for him.

Here's what Cindy wrote in an email today (Oct 25):

"I found this on the internet.

"After school these students have nothing to do except fighting and bullying their schoolmates.

"What is the school teaching them? Fighting? Or how to be gangsters?"
