VANCOUVER, Wash. – Authorities say hundreds of ballots were burned in an arson attack at a ballot box in Vancouver on Monday morning.

KATU was on the scene shortly after 4 a.m. at the Fisher's Landing Transit Center in Vancouver where heavy smoke was billowing from a ballot box.

Our photographer captured gray smoke rising steadily from the park-and-ride ballot drop box at Fisher's Landing Transit Center near Southeast 162nd Avenue shortly after 6 a.m

Several police units were in the area and the ballot box was cordoned off with police tape as smoke continued.

Around 6:30 a.m., KATU captured footage of first responders throwing a pile of actively burning ballots onto the ground, which continued to smolder and smoke heavily even after the flames were extinguished.

The Clark County auditor told us the last ballot collection at that location was at 8 a.m. Sunday. There were hundreds of ballots inside at the time of the burning, and KATU was told that only a few might be able to be saved.

Voters who cast their ballots at this location after 11 a.m. Saturday must IMMEDIATELY contact the Auditor of Elections office to receive a new ballot.

Vancouver police released the following statement at 9 a.m.:
