An 18-year-old man is facing charges and police are seeking two other suspects after a bus driver was allegedly attacked in Dartmouth Tuesday evening.

Halifax Regional Police responded to the bus terminal on Nantucket Avenue before 9:30 p.m.

Police say the 44-year-old bus driver got out of his bus to break up a fight between two young women, but he was quickly surrounded by a group of youths.

“He approached them, attempted to break up the fight, then he was jumped by three other males in their late teens,” says Const. Pierre Bourdages of the Halifax Regional Police.

Police allege three males assaulted the driver, knocked him to the ground and kicked him in the face.

When security personnel at the terminal failed to intervene, other Metro Transit bus drivers stepped in to help.

“All he was trying to do was be a Good Samaritan,” says Shane O’Leary, vice-president of the Amalgamated Transit Union.

“Security failed him. There were no supervisors on hand at the moment because they can’t be everywhere, but the only reason the assault stopped was three other drivers had stepped up to help him.”

The suspects fled the scene and the bus driver was taken to the Dartmouth General Hospital for treatment of minor injuries to his face. He has since been released but is still shaken, and is recovering at home.

Police arrested an 18-year-old male at the bus terminal at 11 p.m. Tyler Power is facing charges of assault causing bodily harm, breach of a recognizance, and three counts of possession of a controlled substance.

Investigators are reviewing surveillance footage as they search for two other teen suspects in connection with the incident.

Meanwhile, bus passengers at the terminal in Dartmouth are expressing concerns for the injured driver, as well as for their own safety.

“I think it’s appalling, you know. Something’s got to be done about it,” said one passenger Wednesday. “There’s a lot of people take the bus and, you know, the drivers need to be protected.”

The Nantucket stop in Dartmouth is the busiest terminal in the Halifax Regional Municipality, with more than 20,000 passengers passing through its gates daily.

The violent incident has the Amalgamated Transit Union calling for change.

“We were told by a senior member of management this morning that security is not there to interact. They are there to observe and call for help,” says O’Leary.

“Busiest terminal in HRM and security guards are not allowed to intervene. That’s wrong.”
