BRANDON, Vt. (AP) – Students at the Otter Valley Union High School will be back in classes Friday while police continue to look for the person who set the smoky fire that could have caused up to $100,000 in damage.

Brandon police say they have leads in their investigation into who was responsible for setting the fire in the women’s bathroom.

“Somebody’s angry, somebody’s acting out, somebody’s taking their feelings out against the system,” said Otter Valley Principal Dana Cole-Levesque.

The fire occurred a year after another fire was set in a bathroom wastebasket at Otter Valley. However that fire didn’t do as much damage.

Cole-Levesque said he didn’t think the two fires were related.

“This is very different. From what we can tell it’s a very different kind of incident,” he said.

“It was very smoky, thick black smoke,” said Brandon Police Officer Benjamin Herrick.

Police aren’t saying much about the progress of their investigation or giving people access to the bathroom turned crime scene.

“We don’t want people to see what’s in there because we don’t want to give anything away,” Herrick said.
