Justin Bieber’s manager says the pop star’s meltdown in 2014 was “worse than people realised”.

Speaking to the Wall Street Journal, Scooter Braun said he feared for the singer’s wellbeing at the time.

“I failed him day after day. We were living in hell because he was in such a dark place.”

2014 was a year to forget for Justin Bieber which included being accused of smoking marijuana and taking prescription drugs.

He was arrested for being involved in what police described as an illegal street drag race in Miami and linked with an attempted robbery in LA.

In April, Justin Bieber posted an Instagram photo of the mugshot from his arrest in Florida.
