It’s possible you may have used a fraudulent transit pass over the past few years.

A man has been arrested a year after an investigation began when transit officers noticed an increasing number of high quality, but forged, U-Pass stickers — which are used by post-secondary students.

In January, more than 3,000 passes, professionally printed in China, were intercepted at the Canadian border.

The fake passes could have resulted in a loss of more than $1 million in revenue to Calgary Transit.

31-year-old David Philip Smerd was arrested last week and charged with fraud.

Police allege that over the past three years, Smerd exchanged fraudulent U-Pass stickers with Calgarians for a total of about $34,000.
