TORONTO - Ontario's lottery and gaming corporation has called in the police to investigate a retailer who won over 160 prizes in nine years amounting to more than $1 million.

OLG says it is not aware of any evidence of wrongdoing in the case, which involves a retailer in northwestern Ontario. But the Ontario Provincial Police have been asked to investigate the unusually lucky lottery seller.

OLG says it has had an independent auditing firm reviewing past winner files, including lottery wins by retailers going back to 1995.

Any other findings that suggest criminal behaviour on the part of some winners will also be turned over to police.

The provincial lottery corporation has implemented a number of security measures after investigations showed too many retailers were winning too many large jackpots.
