Surveillance video from a Kansas City Metro bus captured a shocking incident on Oct. 1, in which a young man appears to sucker punch a driver for no apparent reason.
Police in Missouri are now searching for the suspect and are urging anyone with information to contact them.
The Huffington Post spoke with Captain Steve Young of the Kansas City Police Department, who said that the suspect, who looks to be in his late teens, appears to have entered the bus without paying his fare. Upon exiting, the young man punches the bus driver, seriously injuring him.
According to the descriptions of the videos, which were posted to the KCPD's YouTube channel, the man was "knocked unconscious." Toward the end of the video, the disoriented driver can be seen slowly driving the bus into a barricade.
Young called the blow a "cheap shot" but said the department has received a large number of tips and is optimistic that the suspect will be found.
Bus drivers have been assaulted by young people before. In August, a New York teen was filmed punching a bus driver in the Bronx. In New York, it is a felony to assault a Metropolitan Transit Authority employee -- an offense punishable with up to seven years in prison.
Anyone with information is asked to contact the KCPD's TIPS hotline at 816-474-8477.
