A number of the city's street kids — a group already in the sights of Mayor Charlie Hales and the Portland business community for aggressive panhandling tactics—added unfortunate fuel to that fire today.

According to a release from the Portland Police Bureau, a "large group of transient 'street kids'" assaulted a 70-year-old employee of the Portland Outdoor Store this afternoon at Southwest Third and Oak. One suspect hit the man in the head with a skateboard.

Here's the release:

This afternoon, Monday July 15, 2013, at 2:30 p.m., Central Precinct officers responded to Southwest 3rd Avenue and Oak Street on the report of an assault outside the Portland Outdoor Store.

Officers and medical personnel arrived and located the 70-year-old male victim suffering from a head injury. He was transported to a Portland hospital for treatment to the non-life-threatening injury.

Witnesses told police that a large group of transient "street kids" were involved in the assault of the man, an employee of the Portland Outdoor Store. Witnesses told police the victim was hosing off the sidewalk when he was attacked.

Officers recovered a skateboard possibly used in the assault but have not identified the suspect. One person was arrested on an unrelated warrant.

The suspect is described as a white male in his 20s not wearing a shirt, blonde shaggy hair above the shoulders.

Anyone with information about this incident is asked to call Assault Detectives at (503) 823-0400.
