Edmonton police are issuing a warning to Justin Bieber fans about an online ticket scam ahead of the pop star’s highly anticipated concert set for October 15th at Rexall Place.

Police say two fraudulent Bieber tickets were sold for $800 on Kijiji in Edmonton. Officers report it was a cash transaction and the buyer and seller met in person.

Police say the scam is not unique to Edmonton, as there have been victims in other parts of Canada and abroad.

 “While one person has come forward, we suspect there are a lot more victims. Most people who do fall prey to this type of scam realize they should have known better and are often too embarrassed to come forward to report,” said Detective Dave Radmanovich with the Edmonton Police Service.

Police are warning people about buying tickets online for any concert, and add they will also be on the lookout for fraudulent Metallica tickets.

Police suggest finding out who the ticket seller is first, and ask for identification.

Officers say if the ticket seller is unwilling to provide their name, assume they are not who they say they are.
