UPDATE: Pasco Police said a full sweep of all Columbia Basin College campuses is complete and no explosives were found. Authorities are still actively searching for the caller who made the bomb threats.
CBC President Rich Cummins said the school has a protocol for situations like a bomb threat so they knew exactly what to do and they did it quickly.
"We evacuated the campus. I issued that order, sent out the protocol, issued that emergency notification thru text, through alerting our building captains who went around and cleared the building," Cummins said.
"We, currently, the Pasco Police Department, are working the investigation and working, trying to track down who the caller is. And we're working on that and hopefully going to make some progress with that in the next several hours trying to figure out who their caller actually is," Captain Jim Raymond said.
BREAKING: Pasco Police say all Columbia Basin College campuses have been evacuated due to a credible bomb threat.
CBC says someone called and left the threat in a message on a CBC employee's voicemail at the Pasco campus just before 11:30 Thursday morning.
For the safety of the students, the school has evacuated the Pasco/Richland/Chase campuses until police can investigate. CBC sent emails and texts telling students to leave campus around noon.
At the school's main campus, the entrances to the parking lot are currently blocked off with maintenance vehicles.
The school says the campuses will be closed for at least the rest of the day.
CBC says it will provide more information as soon as possible. We have a reporter on the scene.
