Four youths have been convicted of charges stemming from armed bank robberies and an attempted bank robbery in Mississauga in 2018.

All four were teenagers at the time of the robberies.

The two 2018 armed robberies occurred on May 10 and 25 at different Scotiabank locations in the city. Three of the four youths, who cannot be identified by law, were convicted of charges related to the May 10 robbery.

The same three were charged in relation to the May 25 robbery. Ontario Superior Court Judge Allison Dellandrea found that two of those teens could not be identified beyond a responsible doubt as the masked suspects in the incident.

One was convicted of charges stemming from both the May 10 and May 25 robberies, and the attempted robbery of another Scotiabank on June 15, 2018.

All of the arrests followed the failed robbery on June 15, 2018, which involved a police “takedown” of three of the young people, according to the court decision.

In her Nov. 18 decision, Justice Allison Dellandrea noted Peel police began “extensive surveillance” on three of the four people believed to be involved in the May robberies.

The surveillance operation brought police to a townhouse complex on June 15, 2018, where they followed a Pontiac with four youths to a Scotiabank, the decision said. Once the car — which was reported as stolen in Peterborough four days earlier — stopped in front of the bank, two of the occupants, carrying a bag with their faces and hands covered, approached the doors.

Realizing the bank doors were locked, the would-be robbers ran back to the Pontiac, and police moved in to make arrests. Police drew their firearms and used Tasers during the arrest, which included “extracting” three of the four occupants from the car, the decision said.

Police recovered a large kitchen knife from the car, and a mallet on one of young persons arrested.
