Riders of the Canada Line were shocked to learn last month that somebody had placed a credit card skimmer at two stations.

Today, a photograph of a person of interest has been released.

The transit police force wants the public's help in identifying the man, who's described as a white male, 30 to 40 years old, and 6'1" to 6'2" in height.

He has a thin build, medium-brown hair, and is clean-shaven.

At the time the photo was taken, he was wearing pointed dress shoes and a navy blue blazer, and was carrying a man's courier bag.

The credit card skimmers were detected at the Vancouver International Airport and Vancouver City Centre stations.

"Forensic analysis determined the skimmers were comprised of two parts; the camera portion, which is used to film people entering their cards security PIN and the card reader portion, which collects data from the card," Transit Police said in a news release. "The card reader was equipped with Bluetooth capabilities with a range of approximately 10 meters. The camera required a micro secure digital card (Micro SD card), which would need to be physically removed from the skimmer in order to retrieve the acquired video."

According to the agency, it's "highly unlikely that any credit card or debit cards were compromised".
