UPDATE:

Two bicyclists were riding near a pick-up truck on the 5200 block of California Ave. and words were exchanged among the cyclists and truck driver.

Two witnesses told the West Seattle Herald that it initially appeared that the bike riders were friends with the truck driver because they were all conversing and at one point one cyclist grabbed the truck bed. Then an argument ensued and police arrived. One witness believes the bicyclist hit the truck which provoked the incident.

We will update.
