Justin Bieber seems to be back to his infamous naughty self again. The singer recently created quite a chaos at Radio 1 that he visited for an interview.

Recent reports stated that the singer arrived at the radio office for a chat with host Nick Grimshaw. During the visit, he was shown to a disable toilet to freshen up which were fitted up with a cord fitted with an alarm and marked as "Do not pull."

The 21-year-old reportedly got curious and allegedly pulled the cord which set the alarm bells ringing in the building.

"We had Bieber panic on. He set off the alarm by pulling the emergency cord," Grimshaw told Mirror before adding that Bieber told him he just wanted to pull the cord once.

Earlier, the "Baby" hitmaker made headlines when he left the stage abruptly in the mid of the concert in Oslo, Norway, when fans allegedly tried to come in his way and heckled him while he was trying to clean the mess on stage created by a front row audience member, Daily Mail reported.

After pleading the fans for a couple of times, the singer evidently could not take it anymore and left the stage, declaring, "I'm not doing the show." Later he took to Instagram to apologize for his temper while declaring that he will make up the lost time in his next tour.      

Meanwhile, the singer dropped a remixed version of  "Hotline Bling," originally written by Drake. Bieber released the track on his social media accounts.
