The 43 year-old Watsonville man, who is believed to have caused an accident in which a California Highway Patrol motorcycle officer and another driver were injured, was arrested today. The accident, which also involved a 3rd vehicle, occurred about 3 weeks ago on highway 1 near the fishhook in Santa Cruz. Since both the motorcycle officer and the driver of the 3rd vehicle were injured, Alfredo Saucedo Junior faces charges of Reckless Driving Causing Injury.
