Tuesday around 9:30am students at Prosser High School were sent to Hausel Middle School after a suspicious device was found outside.

The object, according to police statements to the Yakima Herald, was a 'small' thermos type of object, and was noticed outside the school around 7:50am.

The Richland Bomb Squad was brought in, and a bomb sniffing dog went through the building to check for any additional items. The object itself was taken away by the bomb squad and Federal ATF officials are investigating.

Prosser police said the device was a "small bomb." No elaboration was given as to what the potential explosive capability of the object was. More information expected to be released.
