Numerous Toronto police officers have been arrested in a sweeping probe that involved allegations of drug trafficking and auto theft.

The details were confirmed by a source with direct knowledge of the case. The Globe and Mail agreed not to name the source, who was not authorized to publicly release details.

The people accused also include individuals who are not police officers. The source said the police expected to release more information.

The Toronto Police Service declined to comment, but noted in an email that York Regional Police had scheduled a news conference for Thursday.

York police issued a media advisory about an investigation dubbed Project South, which it described as related to “organized crime and corruption.”
