At the FNB Stadium in Johannesburg, criminals chiseled a tunnel into the safe room, lowered themselves down with ropes, and took an estimated $330,000.
The cash came from both the 19-year-old pop star's show and Bon Jovi's concert the night before. No suspects have yet been identified.
Though police believe the crime was an inside job, the "Beauty and a Beat" singer affirms that he wasn't involved. Catching wind of the heist, the Biebs reportedly tweeted to TMZ, "It wasn't me."
