(AP) - Officials say complaints have been filed alleging that Nevada's state prisons chief threatened during a meeting to use a shotgun to kill about 20 employees.
Corrections Department Director Howard Skolnik acknowledged that complaints against him went to the public integrity unit in the state attorney general's office and to the state inspector general's office.
Skolnik says he can't comment because the investigation is ongoing.
A spokeswoman for state Attorney General Catherine Cortez Masto says Las Vegas police are investigating a separate complaint.
An administrative aide at High Desert State Prison alleged that Skolnik threatened during a February meeting to shoot employees whose names kept coming to his attention.
The woman alleged Skolnik created a hostile work environment.
The complaint was signed by several other prison employees.
