PINOLE -- A 54-year-old man was taken by helicopter to John Muir Medical Center in Walnut Creek after he crashed his bicycle and injured his head, authorities said.
The crash was reported around 3:15 p.m. near the intersection of San Pablo Avenue and Del Monte Drive, according to Battalion Chief Andrew Steffens of the Contra Costa County Fire Protection District. The man was unconscious when paramedics arrived, and seemed to be "altered" once he regained consciousness, Steffens said.
A Life Flight helicopter landed at a nearby intersection and took the man to the hospital. An update on his condition was not immediately available.
