VANCOUVER, WA (KPTV) -
A bomb threat forced the evacuation of the Clark County Courthouse Thursday and it appeared to be part of an alarming trend around the state of Washington.
Deputies said the threat was called in by a man at 3:20 p.m. to the Clark County Superior Court Clerk's Office. The caller stated explosive devices were in the courthouse and they would be going off in 20 minutes.
The courthouse was immediately evacuated, but no such devices were found.
After the timeline presented by the caller had passed and the courthouse was thoroughly inspected, the building reopened.
There is no suspect information in the case, according to investigators.
Washington State Police confirmed to Fox 12 a number of similar calls made throughout the day. Bomb threats were called into courthouses in Adams, Columbia, Douglas, Pacific and Thurston counties.
KIRO TV in Seattle also confirmed additional threats made in Benton and Chelan counties Thursday.
Clark County deputies said they expect to look into the cases collectively on Friday when law enforcement agencies from each jurisdiction can compare the situations.
So far, there are no reports of any suspicious devices found linked to these calls.
