Hit-and-run driver injures bicyclist in Center City

A female bicyclist was critically injured in a hit-and-run accident in Center City earlier tonight. The victim, whose age wasn't available, was struck by a pick-up truck at 22nd and Market streets about 7:20 p.m., police said. She was admitted to the Hospital of the University of Pennsylvania in critical condition, although the extent of her injuries was unclear.

Police arrested the motorist a short while later near 22nd Street and Ben Franklin Parkway, said an investigator from the police Accident Investigation Division. The driver, who wasn't identified, might have been drunk, the investigator said.

Update: An investigator said part of the accident was witnessed by a SEPTA police officer, who followed the fleeing driver with another witness. The driver is "an elderly man, who pulled over because he realized he was being followed," the investigator said.
