Local performer Robbie Turner was walking on the corner of Pine and Harvard Thursday afternoon when he said he was attacked.
"I was hit in the face before I even said hello," Turner said.
Police say the attacker caught Turner off guard and punched him in the face.
In February, Turner actually hosted a self defense course after several people were attacked in Seattle. But all that training couldn't protect him from a knife.
"He literally almost cut my throat," Turner said.
On top of everything else, Turner said no one tried to help him as the attacker stole his phone and ran away. Shaken, Turner went to a nearby store and called police.
"It made me feel really alone. If something were to happen, no one would come to your aid," Turner said. "The police officer told me I was the only call that came in."
Police say witnesses either didn't want to get involved or didn't see what was happening.
"In situations like this we don't want people to put themselves in harm's way, but be a good witness and call 911," said Renee Witt with the Seattle Police Department.
Turner hopes the next time someone sees an attack, they take action. In the meantime, he said people should learn self defense.
"So you know you're safe, because at the end of the day the only person looking out for you is you," he said.
Social Outreach Seattle is planning a May 22 Rally and march on Capitol Hill as a sign of solidarity and a sign that no one should feel alone in a dangerous situation.
