Police in the Illinois suburb of Wilmette say Sinead O’Connor is safe after they revealed earlier Monday they had been searching for the singer.

"O'Connor has been located," a statement from law enforcement read. "She is safe and is no longer listed as a missing/ endangered person."

O'Connor was reported as missing to police after she went on a bike ride on Sunday morning and had not been seen since. 

“A caller has expressed concern for her well-being and no other information is available at this time,” a press release from the police department stated earlier Monday. The release was titled “Check for Well-Being.”

On Sunday, O’Connor changed the cover photo on her verified Facebook page. The image she posted was of Harriet Tubman along with a quote that read “I had reasoned this out in my mind, there was one of two things I had the right to, liberty or death; if I could not have one, I would have the other.”

The singer last posted on Facebook on Sunday around 9 a.m. The time zone associated with O'Connor's post was not immediately clear.

Her post was a rambling message to her family.

“Jake, kindly go to the court on Tuesday and take custody your brother from Tusla. My lawyer will be making the illegal way yourself and Donal got him into Tusla (lying to the cops etc) known to the judge. expect to be in trouble. In fact you'd best bring a lawyer of your own. And do not abandon your brother or any other of my babies again. What you have done to your brother and your mother is LITERALLY criminal.”

On May 6, news broke that O'Connor was being sued for libel by Arsenio Hall over a Facebook post she wrote that stated investigators looking into the supplier of drugs used by Prince should question Hall. She also accused him of drugging her.

The lawsuit seeks more than $5 million in damages but any award would be decided by a jury.

In November 2015, O’Connor was hospitalized after an apparent suicide attempt.
