"They were in a little car park area by the sports field."
Kelston Boys High School principal Brian Evans was on his way to the school when the Herald rang him.
"I know absolutely nothing about it. I'm just going there now, I saw it on your website."
He said there were no sports matches scheduled for today.
"The school's open on Sunday morning, there is a church that uses the school, so the school was open but I'll go and try find out myself what's happened."
