Chase ends

Acting Senior Sergeant Bruce Bowers said police were at the station for another matter when they were alerted to the bus incident about 11.10am on Tuesday.

Officers allege the 34-year-old man initially tried to steal money from the driver who resisted.

The man allegedly struggled with the Transperth employee before spitting at him and taking cash.

Sen-Sgt Bowers said police detained the suspect after a short foot chase.

“It was good police were in the area at the time and able to defuse the situation quickly,” he said.

Officers charged the man with aggravated robbery.
