An ACTION bus driver was assaulted in Woden on Sunday by a man who caused a disturbance to other passengers. 

The female driver was preparing to drive passengers on an express service from the Woden Bus Interchange to Civic about 12pm when she asked a male passenger to leave the bus.

The man, thought to be in his mid-20s, allegedly punched her in the face.

The driver was injured in the incident and left bloodied inside the bus.  

One witnesses, who asked not to be named, said the man had been disturbing passengers waiting for the bus and was angry when asked to leave the vehicle by the driver. 

"He was there annoying everybody and carrying on stupidly while we were waiting for the bus and when it came... he was still in the queue annoying people," the witness said. 

"When he got to the driver, he started making stupid comments to her. He lashed out when she asked him to get off the bus and just punched her in the face."

ACT Policing officers and ACTION staff attended the scene. 

"After he got off there were a lot of people around and he was throwing punches at them but didn't hit anyone," the witness said.

"Then he disappeared before the police got there. It was very nasty," the witness said. 

An ACT Policing spokesman confirmed the incident and said a man had turned himself into police on Sunday afternoon.
