Sarnia police say four people have been arrested and 90 fraud-related charges laid in an investigation involving Lambton Mall gift cards.
The criminal investigations branch found that 22 gift cards, valued at over $16,000, were bought online with stolen and compromised credit cards from Canada, the U.S., Spain and Qatar.
Police say charges were laid based on video surveillance allegedly showing the accused people picking up the pre-paid gift cards at the mall.
The offences, during November 2015, forced Lambton Mall to shut down all online gift card purchases and the service remains suspended.
Four others from Sarnia, Sombra, Strathroy and Parkhill were charged.
Police say they're seeking warrants for three remaining suspects.
