The "busjacking" took place in the 4200 block of Minnesota Ave, in Northeast D.C.
The suspect assaulted the driver and stole the bus, according to police. He was originally a passenger, but he started an altercation with the driver and used a non-specified weapon to take over the bus.
The bus driver exited the bus when forced and the suspect sped off, according to police, and that is when the pedestrian was hit.
The bus struck the pedestrian in the parking lot of the Crown gas station.
District of Columbia Police Chief Lanier told the media that the suspect is in custody.
The pedestrian's identity will not be released until next of kin are notified.
