UPDATE: The all-clear at Innes CLC was given just before 12:30pm Wednesday.
District spokesman Mark Willamson says a search of the school by police dogs turned up nothing suspicious and classes resumed. He says there will be beefed up security at Innes over the next couple of days.
(Previous coverage) Innes CLC is on lockdown after a specific threat was uncovered.
APS Spokesman Mark Williamson says the threat was posted on the wall of a girl's bathroom just before Noon Wednesday, prompting the lockdown procedure.
Williamson did not specify the details of the threat.
Classes will resume once the lockdown has been lifted, but Williamson says they take each threat seriously.
