UPDATE FEB. 22: Classes resumed at a high school in northeast Nevada a day after an anonymous threat prompted its closure.
Elko County school officials canceled classes Wednesday at Elko High School after the unspecified threat was received the night before.
The Elko Daily Free Press reported Thursday that local police determined the threat was not credible but that an investigation into the incident was continuing.
School Superintendent Jeff Zander said police were still interviewing some students and reviewing their cellphones.
He says the district purposefully erred on the side of safety by canceling classes on Wednesday because there wasn't enough time to determine whether there was any potential danger.
ELKO, Nev. (AP) -- Authorities in northeast Nevada are investigating an anonymous threat that prompted the closure of the high school in Elko.
The Elko Daily Free Press reports Elko County School Superintendent Jeff Zander decided to cancel classes and close Elko High on Wednesday based on the threat received Tuesday night.
He posted a statement on the district website that says they are working with local law enforcement to determine the credibility of the threat. No other details have been released, but Zander said they hope to know more by Wednesday night.
Zander says protection at other schools in the district was increased Wednesday and would continue the rest of the week because of the threat. He says safety remains a top priority throughout the rural district along U.S. Interstate 80 about 100 miles west of the Utah line.
