Superstar DJ Avicii's brother was en route to Oman to check on the fragile star when he reportedly took his own life, a source has claimed.
The source told People that "Avicii's family spoke to him on the phone earlier that week and got very worried about his mental state".
"His brother flew to Oman to bring him home and arrived only a couple of hours too late."
The Swedish musician, whose real name was Tim Bergling, was found dead at the age of just 28 in the city of Muscat in Oman on April 20. He was reportedly staying on an estate owned by the country's royal family.
Entertainment website TMZ, quoting "sources privy to specific information about Avicii's death", reports the DJ died from a self-inflicted injury.
Tragically, the Stockholm-born Avicii had been battling ill health for years.
He announced in 2016 that he would no longer perform live, following years of health problems caused by stress and alcohol abuse, as well as severe anxiety.
At the age of 21 he was diagnosed with acute pancreatitis, due in part to excessive drinking.
In 2014, he was forced to have his gallbladder and appendix removed.
The superstar made millions during his career but famously said he didn't need that much money.
His devastated family confirmed last week in a poignant statement that he had left a suicide note and revealed that "he couldn't go on".
The statement, translated from Swedish, read: "Our beloved Tim was a seeker, a fragile artistic soul searching for answers to existential questions. An over-achieving perfectionist who travelled and worked hard at a pace that led to extreme stress.
"When he stopped touring, he wanted to find a balance in life to be happy and be able to do what he loved most — music.
"He truly battled thoughts about meaning, life, happiness.
"Now, he could not go on any more. He wanted peace.
"Tim was not made for the machinery he ended up in; he was a sensitive guy who loved his fans, but shunned the spotlight," the statement read.
"Tim, you will forever be loved and missed. Who you were and your music will carry on the memory of you. We love you, the family."
