Two pedestrians were hit and injured by a van and bus in separate accidents within a 24-hour span in San Francisco, police said.
In the most-recent incident, a bus near the Caltrain station in San Francisco's South of Market neighborhood struck a pedestrian Friday morning, according to police and fire officials.
The 42-year-old male pedestrian was struck at the intersection of Fourth and King streets shortly after 10 a.m., according to San Francisco police spokeswoman Officer Grace Gatpandan.
Gatpandan said that the person who reported the collision said the pedestrian was struck by the bus and then "fell on the ground and was bleeding heavily."
San Francisco fire spokeswoman Jen Balestrieri said the bus that struck the pedestrian was not a San Francisco Municipal Railway bus.
According to Gatpandan, the bus is registered to a private bus company and the collision was not a hit-and-run.
Police said the intersection was subsequently closed and reopened to traffic about half an hour later.
Balestrieri said the pedestrian was transported to the hospital with injuries that are not considered life-threatening.
Police investigators are working to determine the cause of the collision, Gatpandan said.
In Thursday's collision, an 18-year-old woman suffered head injuries when a van struck her as she was walking in a marked crosswalk in San Francisco's Richmond District on Thursday afternoon, according to police.
Shortly after 1 p.m. Thursday, the pedestrian entered a marked crosswalk on Fulton Street, at the intersection with 32nd Avenue near Golden Gate Park, and was struck by a white van traveling west on Fulton Street.
Traffic traveling on Fulton Street through that intersection has neither a traffic light nor a stop sign, but must yield to pedestrians in the crosswalk.
The woman was transported to San Francisco General Hospital with head injuries that are not considered life-threatening, police said.
The driver, identified as a 54-year-old man, failed to yield to the pedestrian but has not been arrested, according to police.
