Three males broke into Houston Secondary School and North Star Performance last week.
Police arrested the suspects and are looking for a fourth.
RCMP Sergeant Stephen Rose says the suspects smashed the main HSS door to get into the school, setting off the security alarm at 11:55 p.m. Jan. 17.
They stole cash from the school office and then fled through the emergency exit.
Three days later, just after midnight Jan. 20, the security alarm at Northstar Performance was set off.
Sgt. Rose says police found tracks around the building and a broken window, with two suspects inside.
Both were arrested for break and enter.
Through investigation, police learned of a third suspect who was arrested at his home the next day.
Police are also looking for a fourth male from Prince George suspected to be involved in the HSS break in.
Police suspect the three Houston males are responsible for the series of break and enters over the last three months at HSS and Nadina Truck Service.
They recovered some stolen property from the males, including tools and electronic devices from the high school and Nadina.
Two of the males are youth and their names cannot be released.
Collectively, the three males face over 19 criminal charges, including break and enter, theft, possession of stolen property and mischief.
They were released on conditions including no contact with co-accused and a daily curfew.
