Four cyclists were struck by a vehicle while riding in unincorporated Marin County Saturday, and Marin CHP now say they have arrested a suspect who they believe is responsible.

The incident happened on Point Reyes-Petaluma Road just west of Hicks Valley Road just before noon Saturday, as ABC 7 reports, and the cyclists say that a dark blue Dodge Ram swerved into them intentionally.

All four were injured but one of the cyclists had to be flown to a hospital with severe injuries.

CHP officers say they were sent "numerous tips" that led them to a home in Novato where an arrest was made, and the photo above was posted, around midnight last night.

The Marin Independent Journal reports that the cyclists were participating in the Jensie Gran Fondo of Marin, a cycling event that benefits the Marin Bicycle Coalition.

The Marin CHP writes, "We are grateful to serve a community that looks out for one another. Often times in situations like this people think they see something but often dismiss it as an unlikely coincidence. When we ask for help we are asking you to disregard that feeling and let us know. Sometimes it's the smallest detail that leads us to a suspect."
