More than two dozen people were arrested after what York Regional Police are calling their largest organized crime take down.

The arrests came after an 18-month long investigation involving the Figliomeni family from Italy that was allegedly operating in the GTA for about three decades.

Chief Eric Jolliffe says the investigation dubbed, “Project Sindacato,” was launched after the force noticed a spike in crime in Vaughan and involved about 500 officers from eight police forces across the province, including Durham police.

During the course of the investigation, police say the criminal organization was acting under the direction of Angelo Figliomeni.

Its criminal activities included illegal gaming operations as well as an extensive money laundering system to hide the immense profitability from these activities.

They executed 48 warrants at residences, businesses and cafes across the GTA.

As a result, nine people were taken into custody and more than $35-million dollars in offence-related property and proceeds of crime were seized.

Some of the property seized includes more than $1-million in currency, 27 mafia-owned homes and 23 high-end luxury vehicles.

Police say in total 27 people arrested.

“These arrests signify the fall of power for the most significant ‘Ndrangheta crime family operating in York Region,” said Jolliffe.

Investigators also worked with the Italian State Police and on Thursday warrants were executed in Calabria, Italy, where multiple arrests were made.
