A man on a scooter fell and was injured after suffering an apparent medical emergency while riding.

The incident happened around 3 p.m. on Fairfax Drive near the Ballston Metro station.

A witness said she saw a man and woman riding Bird scooters down the street when the man started having what appeared to be a seizure. He fell onto the pavement and started foaming from the mouth, while his companion yelled for passersby to call 911, according to the witness.

Firefighters responded to the scene and the man was quickly put on a stretcher and loaded into an ambulance. He was conscious and talking to first responders, witnesses said.

A firefighter cleared both of the scooters from the Fairfax Drive bike lane as the man received medical treatment. One lane of traffic was blocked by the emergency response.
