An intruder broke into Floyd Mayweather‘s Las Vegas mansion last weekend and got away with several high-dollar items, according to reports.

The boxing champion was in Los Angeles celebrating his 40th birthday at the time of the robbery.

The vandals escaped with $150,000 worth of merchandise, according to TMZ. Mayweather was partying with Justin Bieber, Mariah Carey, and other celebrities. Mayweather’s home is in the Southern Highlands community.

“We still don’t know what exactly was taken,” officer Danny Cordero of the LVMPD office of public information told USA TODAY. “We haven’t gotten a list from the victim of what items were taken.”

The robbery remains and active investigation. Mayweather is currently vying to get in the ring with UFC star Conor McGregor. The 49-0 welterweight champion last stepped into the ring on Sept 12, 2015 when he beat Andre Berto.
