Police are investigating a suspicious fire that was lit at Hastings Boys' High School early today.
Senior Sergeant Greg Bradshaw of Hastings police said there were two other fires lit in the area overnight, which were believed to be related.
"At roughly 12.30 this morning the caretaker at the boy's high school was woken by fire alarms on the property.
"He went and found the tuck shop was ablaze and made sterling efforts to fight the fire himself and he pretty well kept it under control until the fire service got there."
Mr Bradshaw said there was "moderate damage" done to the canteen and the blaze was being treated as suspicious.
He said no one was hurt, as no one was in the tuck-shop at the time "apart from the bad guys".
Hastings Fire Station Officer Mike Manning said three appliances attended the fire about 1am.
