SPOKANE, Wash. -

Two local law enforcement officers, a Spokane police officer and a Spokane County Sheriff's deputy, are under investigation for misconduct and have been placed on administrative leave.

Last Thursday Spokane Police Chief Frank Straub placed officer Jeff Graves on paid administrative leave after being made aware of allegations of misconduct. The police department did not release details of the misconduct allegations.

An internal affairs investigation has been launched by the department while separate criminal investigations by both the police department and Spokane County Sheriff's Office have been launched into the allegations leveled against Graves.

Meanwhile, Sheriff's detective Dale Toliver has also been placed on paid administrative leave pending the outcome of a criminal investigation launched by the Lincoln County Sheriff's Office.

On Monday, Sheriff Ozzie Knezovich was alerted by Lincoln County about an assault near Odessa early Sunday morning in which Toliver is the suspect. Toliver was scheduled to surrender himself to authorities in Lincoln County Friday afternoon on assault and domestic violence charges.

The sheriff said Friday his department will conduct an investigation independent of Lincoln County's criminal investigation to determine if Toliver violated departmental policies.

"This incident will be investigated.  If the allegations are proven, the appropriate actions will be taken.  There is no room for this type of conduct within the Spokane County Sheriff’s Office," Knezovich said in a written statement.
