A bus driver was physically and verbally assaulted by two passengers after he asked a man and woman to validate their myki cards while travelling on May 23.

The 23-year-old man was driving a Ventura bus on the 253 route when he picked up the pair, aged in their 40s, at the Northland Shopping Centre just after 9am.

Upon entering the bus, the pair did not touch on with their myki cards, and, after being confronted by the driver, became aggressive and verbally abusive before sitting at the back of the bus.

The driver attempted to have the passengers return to the front of the bus to validate their tickets a number of times by using the PA system, which they ignored.
