As a motorcyclist rode through the streets of downtown early last Monday morning, a man ran into traffic with a hammer and began to assault the rider, a Seattle police report says. Police responded to assault at at 6:44 a.m. on September 7 near 5th Avenue and Pike Street.

Police interviewed the victim, who explained that he was traveling south on 5th Avenue when the assailant took the 18-to-20-inch tool, “similar to a small sledge hammer,” and knocked him off the bike. The assailant proceeded to hit the motorcyclist while he was on the ground, swinging the hammer at his feet and legs. The victim managed to get up and flee. Witnesses corroborated the victim’s story and say the attack was "unprovoked," the report says.

When officers checked the vicinity, they found a witness who told the officers that he observed the attack and followed the hammering man, who the witness then saw “assault somebody else,” the report says.

The report says nothing about injures, but did mention that the bike was "damaged on its right side " from hitting the street. Seattle police searched the area on foot but could not find the suspect.
