An overnight protest on a closed Washington state freeway ended with two women in the hospital after a motorist barreled into the crowd, according to Washington State Patrol.
For weeks, law enforcement authorities have warned pedestrian protesters not to use the highways as the setting for protests.
"The freeway is simply not a safe place...We feared something like this would happen," said Captain Ron Mead, commander of Washington State Patrol field operations for District 2, at a press conference Saturday morning.
A 27-year-old man from Seattle is accused of driving his car onto the closed I-5, going around the vehicles that were supporting the protesters, and striking the pedestrians standing in the shoulder of the road, said Mead.
"We don't know exactly where the vehicle came on, but we suspect he came on, on the wrong way of a ramp and entered the southbound lane of I-5, he did not come through on one of the closure lanes we had posted," said Mead.
Interstate 5 between SR 520 and I-90 was closed multiple times in the last 24 hours due to protests.
A 32-year-old woman from Bellingham and a 24-year-old woman from Seattle were hit and taken to a nearby hospital.
The younger woman is in critical condition after suffering life-threatening injuries while the other victim is in stable condition.
The unidentified driver stopped the all-white sedan and was taken into custody for questioning. Mead said the driver passed a sobriety test and there's no indication that the car was stolen.
"At the very least, he is looking at vehicle assault charges, felony hit-and-run, but those could be upgraded depending on the progress of the investigation," said Mead, adding, "We don't know if it's a targeted attack, but that remains the focus of our investigation."
Mead said police have made efforts to keep cars and pedestrian separated during protests in order "to try and avoid this."
"As a result, my hope is the protesters will reconsider their desire to be on the interstate. I cannot guarantee their safety, plain and simple," said Mead.
Police are asking anyone with information to contact the Washington State Police.
