A student is in custody after an "active shooter threat" Friday morning at a Prosser middle school.
A 13-year-old reported just after 7 a.m. that a gunman was at Housel Middle School.
But no threat was found when Prosser police and Benton County sheriff's deputies converged on the school. They then checked other schools in town and didn't find a shooter.
Police said they traced the call to a 13-year-old and the student was arrested at the middle school.
The same student was tied to a bomb threat that forced an evacuation at the same school Thursday morning, Prosser police said in a news release.
"These types of calls are taken seriously and are not tolerated," a sheriff's office Facebook post. "The suspect has made three calls in the past two days of this related topic and will be charged with each occurrence."
Prosser school officials said the district will follow heightened security measures for the rest of the day.
On Thursday, Prosser officers went to the middle school just after 7 a.m. after an anonymous tipster called about a social media post "about a bomb being planted in the school," said in a news release later in the day.
Officers immediately evacuated the few employees who already had arrived that morning and also stopped students from coming onto the campus.
A Hanford Patrol bomb-sniffing dog conducted an extensive search, but found nothing suspicion.
Anyone with any other information on the calls is asked to contact Prosser police using the non-emergency number at 509-628-0333.
