The fan turns and shows his bloody lip from the hit.
Bieber's rep did not immediately respond to ABC News' request for comment.
The 22-year-old has been traveling the globe for his Purpose World Tour, which ends later this month in London. After a tumultuous 2014, Bieber and his reputation seemed to be on the mend over the past two years.
"Take this moment to listen and try not to give me a hat or whatever you're trying to throw onto the stage right now," Bieber said in a video taken by a fan. "I probably don't want that s---."
Then last month, he was recorded walking off stage in England when fans wouldn't stop screaming during one of his shows.
“I appreciate love, I appreciate the kind things, but the screaming in these breaks has got to stop. Please and thank you. I don’t think it’s necessary when I’m trying to say something and you guys are screaming," he said before walking off. He later returned and explained that he wasn’t getting respect and courtesy, according to Entertainment Weekly.
