(Portland, OR) -- Police say they've arrested a man seen on surveillance footage driving onto a sidewalk and hitting at least two pedestrians in northeast Portland. Police arrested 21-year-old Austin Keever-Nyberg yesterday after he turned up at the Clackamas County courthouse for an unrelated matter. Police say a home surveillance camera caught him accelerating toward three people walking on a sidewalk January 10th, striking at least two of them. He then appears to pursue the group in his pickup truck. He's now facing charges of first-degree attempted assault.
