At least one person is in critical condition after a motorcyclist crashed into a pedestrian in a Brooklyn crosswalk on Saturday, authorities said.

According to the NYPD, the 48-year-old victim was found unconscious at the intersection of Pennsylvania Avenue and Fulton Street in East New York at 6:30 Sunday morning. He was quickly transported to Jamaica Hospital, along with the driver of the motorcycle, who is expected to survive, police said.

The FDNY, meanwhile, says that three people were transported from the scene to Jamaica Hospital, and that two of them are in critical condition. They could not offer any additional information about the third person, including whether they were a pedestrian or motorist.

The NYPD's Highway Collision Squad is investigating, and we'll update as more information becomes available.
