A silver Ford Mustang was set on fire and emblazoned with the words "FK Trump" early Friday, Portland police said. They're looking for the suspect.

The car was set on fire at Southeast Ninth Avenue and Ash Street about 12:30 a.m., police spokesman Sgt. Pete Simpson said. Witnesses said they saw someone running away.

After the fire was extinguished, officers saw "FK Trump" had been spray-painted on the passenger side of the car, Simpson said. They also noticed a small pro-Trump sticker on the car, Simpson said.

A Volvo in front of the Mustang also was vandalized, Simpson said.

A witness told police he heard what could have been an explosion and saw a person jumping in place by the Mustang. The person then ran south on Ninth Avenue, the witness said. The person was thin, average height and was wearing dark clothes.

Police ask that anyone with information about the crime call 503-823-4357, text 823HELP followed by the tip or submit the tip online.
