SIERRA MADRE — About 80 customers of a Sierra Madre gas station have had their identities stolen, and police sought more victims Thursday, officials said.

The alleged identity thefts took place over the past month at EVG Quality Gas, at Baldwin Avenue and Sierra Madre Boulevard, Sierra Madre police Sgt. Joe Ortiz said.

The gas station closed down about a week ago, he added.

Police learned Monday that customers of the station were having their credit card and debit card numbers used without their permission, the sergeant said. The investigation continued Thursday, when police had identified about 80 victims.

Anyone who has used their credit or debit cards at EVG Quality Gas and noticed unauthorized activity on their accounts is asked to contact the Sierra Madre Police Department.
