Sweden’s Economic Crime Authority confirmed that it had made an unannounced visit to the headquarters of online gambling group, LeoVegas in Stockholm this week. 

The authority has launched a preliminary probe into suspected insider trading of shares in the company.

It has also been confirmed that no LeoVegas employees or members of its executive teams have been notified about any suspected criminal activity. 

LeoVegas said that it would assist the authorities fully with the investigations but said that it was not authorized to reply to any questions regarding the case.

Last month, the US casino operator, MGM Resorts told the market that it plans to acquire LeoVegas for just over $600 million. 

At the time, MGM said that the deal was excellent for its brand since it allowed the group to acquire strategic opportunities to accelerate expansion outside of the US. 

MGM Resorts CEO and President, Bill Hornbuckle said about the acquisition plans last month: “Our vision is to be the world’s premier gaming entertainment company, and this strategic opportunity with LeoVegas will allow us to continue to grow our reach throughout the world.”

“We have achieved remarkable success with BetMGM in the U.S., and with the acquisition of LeoVegas in Europe we will expand our online gaming presence globally.  

LeoVegas has licenses in eight regulated jurisdictions, most of them in North European countries.
