A Metrobus driver was slashed in the face by a rider on his bus in Northwest D.C. Monday.
Metro Transit Police were called to the scene at Albemarle and 40th streets NW in Tenleytown during lunchtime.
Sources say the driver and the suspect got into a dispute about the fare when the suspect hit the driver in the head, then stabbed his face.
Another driver saw the attack and flagged down nearby D.C. police officers. The suspect is described as a 65-year-old man, who was tracked down by police shortly after the incident and charged with assault by a deadly weapon.
The bus operator, who had been driving an H4 bus en route to Brookland, has been taken to a hospital with non-life threatening injuries.
Since 2011, at least 170 Metrobus drivers have suffered on-the-job assaults, according to a report by the News4 I-Team earlier this year.
The details of Monday's attack are unknown. But disputes over bus fare payments triggered a large number of previous attacks, according to incident reports and information from Metro Transit Police.
Many of the attacks have been captured on security camera footage.
