Toronto police are looking for a man who allegedly defrauded the LCBO on at least seven occasions by buying vodka in plastic bottles, replacing the vodka with water, and then returning them to LCBO locations across the GTA.

In January, an LCBO customer discovered that his bottle of Smirnoff vodka was actually full of water.

"I took a swig from the bottle and said to my wife, 'Wow, that's not vodka,'" Rick Crumpton told CBC News at the time.

Toronto police have released a surveillance camera picture of the suspect, whom spokeswoman Jenifferjit Sidhu says has not hit the same location twice. He is described as being six-feet tall, with short brown hair, facial hair, and sunglasses.

"Just the thought that you're making the purchase of a product, be it vodka or anything else, you expect it to be in its original form," said Sidhu.

LCBO spokeswoman Christine Bujold said the suspect used "a new kind of tampering that we hadn't seen before" to perpetrate the fraud.

The LCBO has since changed its returns policy for liquor in plastic bottles, and will no longer stock returned plastic bottles for resale, said Bujold.
