The gang of four allegedly compromised the un-named company's computer system and loaded money onto the pre-paid debit cards before withdrawing the cash at ATMs in Canada and several other countries.

Priscilla Mastrangelo, Jean Francois Ralph and Spyros Xenoulis, all from Montreal, along with Israeli Ehud Tenenbaum are charged with fraudulent use of credit card data and fraud.

The gang were arrested by the Calgary Police Service Commercial Crime Unit following a seven month investigation in co-operation with the Montreal Police Service, the Vancouver Police Department and the United States Secret Service.

All four individuals were arrested in Montreal and transported to Calgary to face charges.
