ALBUQUERQUE, N.M. (AP) — A passenger has been caught on camera attacking and knocking out an Albuquerque city bus driver.

KOAT-TV reports that the video shows a man walking on to the bus and trying to pay with expired bus passes. He then refuses to get off the bus and claims to be an undercover police officer.

The video shows him telling the bus driver to close the door and drive. The driver says the man is holding a knife.

Eventually the man punches the bus driver, knocking him out, and then runs away.

Albuquerque police have arrested a man they say is responsible for the attack.
