More details surrounding Sinéad O’Connor’s sudden death have been revealed.

Police announced Thursday that the “Nothing Compares 2 U” singer was found “unresponsive” at an apartment in London after they received a phone call Wednesday at 11:18 a.m. local time alerting them to an emergency.

O’Connor was “pronounced dead at the scene dead at the scene,” but her “death is not being treated as suspicious,” the Metropolitan Police said.

An autopsy to determine her cause of death will be conducted, with results expected to take “several weeks.”

The late Irish singer, who became just as known for her controversial political actions as she was for her music, died at the age of 56.

“It is with great sadness that we announce the passing of our beloved Sinéad,” her family confirmed in a statement.

“Her family and friends are devastated and have requested privacy at this very difficult time.”

A week before she died, O’Connor sent one final tweet that said she had felt “lost” since her 17-year-old son, Shane, died by suicide in January 2022.

“Been living as undead night creature since,” she emotionally tweeted on July 17.

“He was the love of my life, the lamp of my soul. We were one soul in two halves. He was the only person who ever loved me unconditionally.”

She concluded, “I am lost in the bardo without him.”

The “Troy” singer also tweeted a prayer to ease suffering just weeks before her death.

“‘This is dedicated to the many upon whom I have in my life so far brought suffering and is also, with love, for anyone who has in their lives so far brought suffering upon me,’” she wrote, directly quoting the prayer.

O’Connor made her last public appearance in March at the RTÉ Choice Music Prize, where she looked happy and healthy as she accepted the award for Best Irish Classic Album.

The trophy was given in honor of 1990’s “I Do Not Want What I Haven’t Got.”

O’Connor is survived by her three other children: Jake, 36, daughter Roisin, 27, and son Yeshua, 16.
