Witnesses chased and detained a driver who tried to flee the scene on foot after a van plowed into diners outside a Los Angeles restaurant Sunday afternoon, injuring nine. Police say the driver, who was booked on suspicion of felony hit-and-run, hit people on the sidewalk after running a red light and swerving to avoid another vehicle, the Los Angeles Times reports. Police say they don't believe the driver was under the influence of drugs or alcohol. The van hit several tables of diners at the Fish Spot, a popular restaurant in the Mid-Wilshire neighborhood, KTLA reports. The most seriously injured victim, a 44-year-old man, was hospitalized in critical condition. (More Los Angeles stories.)
