Regina police are investigating after thieves made off with $500,000 worth of liquor that was on its way to a Saskatchewan Liquor and Gaming Authority warehouse.

It happened on Nov. 30 when a trucking company carrying the spirits from Ontario realized it was missing a trailer. 

The trailer was carrying about 1,500 cases of whisky, rum and vodka.

David Morris a spokesperson with the SLGA said nothing like this has happened before. 

"We get between five and 10 truck loads of liquor a day," said Morris. "To my knowledge this is the first time that a truck-load destined for the warehouse was stolen. So this is very unusual."

Police found the empty trailer on Dec. 2 in Regina's east end. 

There is no word on how many suspects are involved or how the thieves managed to get away with the booze. 

Officers are reviewing security footage for leads. 

Morris said he's certain the incident won't affect buyers. 

"If one liquor store doesn't have it we can do an in-store transfer," he said. "They can bring it in from another store that has it free of charge, so certainly there shouldn't be any difficulty with customers getting product."
