The report with details of his death comes from TMZ, quoting 'sources privy to specific information about Avicii's death'.

Last week, his family penned an open letter saying the 28-year-old 'could not go on any longer and wanted peace'.

This Instagram picture of Avicii and friends drinking and posing on a yacht in Oman was posted one day before he took his own life. A source close to the family said: ‘The family was aware that Tim was mentally unwell. It went up and down, but when he was in Oman it got worse'.

The letter, signed 'The Family', described Avicii as a 'fragile artistic soul and a sensitive guy not made for the machinery he ended up in'.

It says he 'truly battled thoughts about the Meaning, Life, Happiness. Now, he could not go on any more. He wanted peace.'

Speaking to MailOnline at the time of the letter's publication, a spokeswoman for the artist declined to confirm whether he had taken his own life.

Swedish entertainment news website Stoppa Pressarna reported that hours before the DJ's death he spoke to a member of his family who was so worried by the phone call that he immediately traveled to Oman, but arrived two hours too late.

‘The family was aware that Tim was mentally unwell. It went up and down, but when he was in Oman it got worse,’ a source close to the family said

‘When they spoke to Tim on the phone, they got worried., The family understood that it was bad and that they had to act.

‘The plane landed two hours after Tim had passed away’.

AVICII'S FAMILY'S OPEN LETTER Read the family's open letter, published on Thursday, in full; 'Our beloved Tim was a seeker, a fragile artistic soul who always carried great existential questions. 'An overperforming perfectionist who travelled and worked hard at a tempo which led to extremely difficult stress. 'When he stopped touring, he wanted to find a balance in life to feel good and be able to do what he loved the most - music.' 'He truly battled thoughts about the 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'. Advertisement

In the days following his death, it was revealed that Avicii had been in a committed relationship with Czech-American model Tereza Kačerová, and was a doting step-father to her young son at the time of his death.

Ms Kačerová posted a heartbreaking open letter on her Instagram, in which she revealed that the pair had been planning on having children of their own, along with a series of photographs of them together.

She writes: 'Every time I think about something we won't finish I feel physical pain in my heart.

'We never finished the Harry Potter marathon - we had the last one left - you never witnessed me having a meltdown when Snape dies.

'I never finished persuading you that our daughter's name MUST be Serafina.

'You never finished your tattoo sleeve in which the inner forearm would have a face coincidentally resembling mine.'

She continues: 'I was always very set on keeping our relationship private because I wanted it to be OURS and ours only and wanted no part in that madness.

'But I thought, if I'm going to share this with the world, it will be when I'm pregnant with our child. Ohhh how that plan went awry.'

Struggles: In Avicii: True Stories, the DJ himself can be heard saying he is 'going to die' if he does not stop performing, and that he has told his management this 'so many times'

Despite a meteoric rise to success following the release of hit-single Le7els in 2011, Avicii announced in 2016 that he would not longer perform live, following years health problems caused by stress and alcohol abuse, as well as severe anxiety.

A recent documentary, Avicii: True Stories shed light on the extreme pressure he was under, performing 320 shows in a single year.

In the documentary, Avicii, a self-confessed introvert, speaks frequently about using alcohol as a crutch to be able to perform, drinking every day during his hectic tour, and to help him with his crippling anxiety and stress.

At the age of 21 he was diagnosed with acute pancreatitis - a potentially life-threatening inflammation of the pancreas - due in part to excessive drinking.

In 2014, Bergling was again hospitalised and forced to have his gallbladder and appendix removed.

Avicii made a fortune during his short career, cashing in $28million in 2014 alone, earning $250,000 a night when playing out sold-out shows, according to GQ.

Avicii himself was less bothered about his millions, saying in 2013 that he 'noticed straight away when I started making money, that I don't need that much money'.

In 2012 he donated the entire income of his U.S. tour - more than one million dollars - to hunger relief charity Feeding America, and in 2013 he gave one million euros to Swedish aid organisation Radiohjälpen.

Bergling grew up in affluent Ostermalm in the Swedish capital Stockholm, and began producing music in high school.

He made a name for himself on the EDM (Electronic Dance Music) scene, before his breakthrough hit Le7els in 2011.

He would later become known for hits like Wake Me Up!, You Make Me, and recently Lonely Together, a collaboration with Rita Ora.

He won two MTV Music Awards, one Billboard Music Award and earned two Grammy nominations.

Just three days before his death, in his final post on Twitter, Bergling thanked the Billboard Music Award's jury for his nomination int the Top Dance/Electronic Album category for his EP Avīci (01).

He died on April 20 in Muscat, Oman, where he is reported to have been holidaying with friends.

An official cause of death has not been made public.
