Justin Bieber’s performance in South Africa Saturday ended in the loss of an estimated $300,000 after thieves robbed the FNB stadium of money from both Bieber’s and Bon Jovi’s performances.

"The suspect had gained entry through the roof," Katlego Mogale, a spokeswoman for the Booysens police station explained to Sky News. "They broke the tile...of the bathroom between last night [Sunday] after the concert, and this morning."

The money in questioned is said have been put in a safe and wasn’t noticed as missing until Monday morning. The thieves were undetected throughout the entire heist.

According to New York Daily News, the plot of the robbery is said to be extremely thought out. The FNB is accused of purchasing fake security guard certificates which causes the facility to vulnerable to attacks.

"You could have very good people, and then the last 50 of 300 or 400 guards are simply just bodies," Jacques Grobbelaar, the stadiums manager said. "This is a concern that we continuously address."

Eyewitness News notes that following the revelation that the money had gone missing the FNB was placed on lockdown for officials to thoroughly investigate the arena.

The exact amount of money stolen is still unclear.
