One man has been arrested after attacking KATU photographer Bob Bullock in an incident that was caught on camera. Bullock was injured while shooting weather video outside Laurelhurst School in Southeast Portland.

In video clips cut by KATU, a man later identified as Peter Fournier is seen approaching Bullock and pressing his back against the camera, blocking its view. Fournier calls Bullock a "loser reporter," preceded by expletives deleted by KATU. Fournier then takes a couple of swipes at the camera. The video jumps to a brief scene of struggle as Fournier looks down, appearing to have his hands on the camera and possibly the photographer, accompanied by sounds of distress.

In KATU's report, Bullock says the man initially told him that he shouldn't be shooting video of children. Later, he ripped the camera's viewfinder off. Fournier was arrested for assault, malicious mischief and impersonating an officer, according to KATU. Bullock reported bruised ribs and a cut up hand.

Fournier had previously been excluded from Laurelhurst Park for using a stun gun on a minor, according to police records obtained by KATU. Fournier admitted at the time that "there was a question as to whether I had exceeded my authority."

We've asked KATU if they will release more video of the incident. The clips posted online come with a disclosure that they were edited for brevity.
