Police are investigating after a daring armoured truck robbery in Rosemont Wednesday evening.

Montreal police say two armed and masked suspects were lying in wait for the security guards making a delivery to the Bank of Montreal branch at the corner of Masson St. and 5th Ave. at about 8:30 p.m.

Police say no weapons were used in the altercation. No one was injured, though one of the Garda employees was taken to hospital to be treated for shock.

"What happened is that two suspects, they were masked and carrying weapons, they controlled two agents who were transporting valuables and fled with the money bag," said Manuel Couture of the Montreal police department.

"Nobody was hurt in this incident but one agent was taken to hospital and treated for shock."

Police set up a large perimeter in the area as they sifted through evidence.

They expect to issue a description of the suspects later on Thursday, meanwhile anyone with information is asked to call Info-Crime at 514-393-1133.

Union wants more staff

This is the third heist of a Garda armoured truck in the past year, and the union says the company is taking unnecessary risks.

The union says Garda used to send three guards on jobs to deliver money.

“The third guard was the one monitoring the situation,” explained Angelique Paquette, president of the union that represents Garda employees.

However the company now routinely sends out just two people to deliver or pickup cash, which the union says makes thefts easier.

It is urging the provincial and federal governments to pass legislation requiring transportation companies to have higher staffing levels.

In a statement, Garda maintains that it can safely operate with two highly-trained armed guards, making the presence of a third guard unnecessary.
