Suspects recruited via encrypted app and offered money for violent acts, Toronto police reveal after arrests.

Toronto police have announced two arrests in connection with the shooting at the US Consulate last month, calling the suspects “criminals for hire.”

Authorities on Thursday said they arrested a 19-year-old man and a 15-year-old boy in the second shooting at the United States Consulate in five months.

The latest shooting in July followed a March 10 attack on the diplomatic mission that also occurred before dawn. Police arrested two people in that case in June.

No one was injured in either event, but police described both as “national security” incidents, and the initial shooting on March 10 prompted beefed-up protection for US and Israeli diplomatic buildings in multiple Canadian cities, as war gripped the Middle East.

The Royal Canadian Mounted Police also opened a parallel investigation, treating the shooting as a national security incident.

Police on Thursday said they believe the suspects were recruited through an encrypted messaging app and were offered money to open fire on the consulate.

“There has been significant public interest and speculation about who is behind these crimes,” Police Chief Myron Demkiw said. “That remains a key focus of our investigation.”

Police identified the adult suspect as 19-year-old Xen-Ul-Abdeen Syed, who faces multiple firearm, arson and stolen-property charges, as well as a charge of attacking the premises of an internationally protected person. A 15-year-old was also charged but cannot be identified under Canadian law.

Since the first shooting, police have maintained a visible presence outside the consulate. The July 27 shooting occurred despite a marked police cruiser stationed nearby.

Police said a white Honda Accord pulled alongside the consulate at about 4:46am (08:46 GMT) and a single shot was fired, striking the front of the building. A brief police chase followed, but the chase was called off when the driver was travelling at excessive speed.

Toronto Police Chief Superintendent Joe Matthews of Detective Operations said investigators believe shootings, homicides and arsons are increasingly being commissioned through online apps, with suspects offered varying amounts of money depending on the crime.

Individuals are hired to shoot at various targets and record the shootings for payment. The targets the police have mentioned included synagogues, Jewish schools, a waste management company, and the US Consulate.

“In many circumstances we know they are not getting paid,” Matthews said.

Police also allege the two suspects were involved in setting fire to a vehicle in a community outside Toronto three days before the latest consulate shooting.

Two men, aged 18 and 19, were arrested in June as part of the investigation into the March shooting. Police said the men were recruited to carry out violent acts, but did not provide further details.
