Two adults and a child standing near a bus stop in Northwest Washington were struck by a vehicle that went up onto a sidewalk, according to authorities with D.C. police and Metro.

One person went up on the hood of the woman’s car, Metro officials said, before coming to rest on the ground. At least one of the victims was in serious condition at an area hospital; officials said the child was hospitalized with a foot injury.

The D.C. police department's major crash unit is investigating the accident, which occurred shortly after noon at Georgia Avenue and Butternut Street Northwest, in the Takoma neighborhood just south of the old Walter Reed Army Medical Center campus.

According to Metro officials, a Metrobus was at stopped at a bus stop when a vehicle heading north on Georgia Avenue with a 79-year-old woman driving came up on the sidewalk and struck the pedestrians.

The vehicle then re-entered the road, cutting in front of the bus, but not hitting it, said Dan Stessel, a Metro spokesman. The woman’s vehicle then hit another vehicle before coming to a stop. Stessel could not say whether the pedestrians who were struck were waiting to board the bus.

Officer Tisha Gant, a D.C. police spokeswoman, confirmed the account given by Metro but said only that three patients had been taken to hospitals for treatment. She could not confirm whether all were pedestrians.
