DURHAM -- The number of people charged in connection with what police describe as a large-scale debit card forging operation continues to grow.

Durham investigators have now busted 17 people alleged to have been involved in the ring. Police say suspects created fraudulent debit cards with data stolen from point-of-purchase terminals.

In the latest round of arrests officers conducted surveillance on a house in Toronto Sunday, looking for a suspect wanted in connection with the investigation. Cops executed a search warrant and seized hundreds of forged debit cards, along with more than $10,000 in cash and materials they say were used to create fraudulent cards.

Police arrested 21-year-old Vigitharan Selvaraj of Toronto, who is the man wanted on charges relating to the original investigation, and four others: Pararajasingam Ampalavanar, 38, of Finch Avenue East, Toronto; Srimylan Srivigneswaran, 20, of Ingrid Drive, Toronto; Prasad Thiruchelvam, 27, of Victoriawood Avenue, Markham and Janarthanan Ratnasingham, 27, of Lawrence Avenue East, Toronto.â?¨ They face numerous fraud-related charges.

The latest round of charges is connected to an investigation in late November that led to the arrest of seven men accused of conducting a card-skimming operation at a Whitby gas bar. When those men appeared for bail hearings in an Oshawa court Dec., 3 fraud cops recognized several suspects they believed to have used fraudulent cards at ATMs among those in attendance. Five additional people were busted at the King Street courthouse on fraud charges.
