Police have released CCTV footage of a young man attacking a bus driver in Brisbane’s east last month.

The footage shows the man boarding the bus at Carindale about 2pm on February 11 before getting into a verbal altercation with the driver about the fare.

After tapping his go card on the machine, the footage shows him lean over the driver and punch him in head twice in front of passengers on the bus.

As the driver goes to stands up, the man then shoves him into the driver’s window before he walks off the bus.

Police said the man also made threats to the driver, who suffered minor bruising and swelling during the assault.

Officers were not aware of any other similar incidents since, a police spokesman said.

On Tuesday, police released footage of the incident and an image of the offender and urged anyone who recognised him to contact police.
