WAIPAHU (HawaiiNewsNow) - The Waipahu classroom arsonists are caught on tape.
Now, police need to catch them in person and your help could score you a cash reward.
They saw the surveillance camera and they still kept going.
For six hours, the tape shows four young men drinking alcohol and lighting fires at Waipahu Intermediate School.
Waipahu Intermediate's principal says they just replaced the cameras because they weren't working properly.
That was just a few weeks ago and now with this arson case, they're glad they made that investment.
It's prompting them to get even more cameras.
It's last week Thursday in the early evening hours at Waipahu Intermediate.
The four suspects, in their late teens to early 20s, are seen hanging out right outside classrooms. This would go on for six hours.
"It looks like they were drinking on campus and then got silly and did something," Waipahu Intermediate School principal Randell Dunn said.
They know they're being watched, as one of the men even throws something at the camera.
Then they start vandalizing the campus, ripping fliers off billboards and attacking potted plants.
Then one man breaks a lighter in front of a classroom and ignites the fluid. The flames flared up, but went out.
But a few minutes later, you can see the glaring lights from the flames coming from a classroom nearby.
The portable was used as a special education resource center and was destroyed.
It's a similar scenario to the fire that happened just days later at Honowai Elementary School.
Sunday Night, police say the suspects there tried to set a few rooms on fire before finally torching one.
And they say it may be the same men involved.
"We know that somebody has to know these four males or can at least identify the males and allow us to talk to them to get information," Sgt. Kim Buffet of CrimeStoppers said.
Dunn says he may have seen one of the suspects on campus on Monday.
"Kind of looked like him, but I didn't say he may be a suspect or not, I'm just saying that people on campus who do hang around, they are all suspects," he said.
No arrests have been made, but police say they are following up on leads.
The combined estimated damage caused from both fires is more than $500,000.
"School is an investment in the future of our state, as well as our government, country and doing these kinds of stuff only hurts us and sends a bad taste in people's mouths," Dunn said.
