Toronto police say a man brought duffle bags filled with cash to an east-end money-transfer business and attempted to send the $520,250 in funds south of the border.
The incident happened June 14 at a business on Lawrence Avenue East, near Warden Avenue.
Police say the duffle bags were filled with $20, $50 and $100 bills. The man who entered the store wanted to send that money, via wire transfer, to a location in Los Angeles.
The business did not complete the transaction and returned only a portion of the money to the man.
Police allege that man and others subsequently made threats and harassed the business owners in an attempt to recover the money.
A second man is alleged to have attended the home of a family member of one of the business owners in July. Police say he made a threat and that the funds were returned to the first man.
Two men were arrested this month, as part of what police describe as an "ongoing money-laundering investigation."
