Police Looking for Bus Driver Assailant

La Crosse police are searching for the guy who tried to punch a city bus driver this weekend.   Cops say the bus video pretty clearly shows a guy on a bicycle yelling at the bus driver while the bus drove down Market street.  The biker then drops his bike in the middle of the street, climbs on the bus, tries to punch the driver and then gets chased back off the bus.  Police say the guy appears to be drunk in the video.
