Sinead O'Connor Found Safe After Daylong Search

WILMETTE (CBS) -- After she was reported missing on Sunday in Wilmette, police have located Irish singer Sinead O'Connor.

O'Connor left on a bicycle around 6 a.m. on Sunday, Wilmette police said. She was found Monday and "is safe and no longer listed as a missing/endangered person," police told CBS 2's Mai Martinez.

Further details were not immediately available.

"A caller has expressed concern for her well-being," police said.

O'Connor had been staying in the north suburb and collaborating with musicians here. She performed March 4 at Metro as part of a tribute concert to David Bowie, singing "Life on Mars" and 'Sorrow."

CBS 2 photo journalist Lou Kleinberg spotted her in the north suburb last week, and posted a picture on Facebook.

The Irish singer-songwriter is perhaps best known for her recording of Prince's song "Nothing Compares 2 U" and her appearance on "Saturday Night Live" when she tore a photo of Pope John Paul II during a live performance.

In November, O'Connor threatened suicide on Facebook and she has been involved in custody battles with her children.

This month, Arsenio Hall reportedly filed a libel suit against O'Connor after she accused him of providing drugs for Prince, who died on April 21.

O'Connor posted a message on Facebook hours before she was last seen on Sunday that appeared to be directed at her oldest son, Jake Reynolds.

According to the Daily Mail, she claimed Jake and her ex, Donal Lunny, had her 12-year-old son Shane placed in TUSLA, a child and family agency in Ireland.

Also this past weekend, she indicated on Facebook that she planned to travel to North Carolina to protest that state's transgender bathroom law.
