Police in a Chicago suburb called off their search Monday for singer-songwriter Sinead O’Connor after she was found safe.

Officer Fred King of the Wilmette, Illinois, Police Department told CNN that O’Connor was located Monday after being missing for more than a day. An unnamed caller had alerted authorities that the singer had not returned from a bike ride early Sunday morning.

Police didn’t offer any details about where O’Connor had been or how they located her.

“The Wilmette Police is seeking to check the well-being of Sinead O’Connor,” said an earlier press release from the desk of Wilmette Police Sgt. Michael Robinson. “O’Connor reportedly left the Wilmette area for a bicycle ride yesterday at 6:00 AM and has not returned. A caller has expressed concern for her well-being and no other information is available at this time.”

The Irish-born singer, who became a global star in 1990 with her Prince-penned hit, “Nothing Compares 2 U,” has had her fair share of troubles in recent years.

Earlier this month former late-night host Arsenio Hall filed suit against her for $5 million, claiming defamation after she accused him of supplying Prince with drugs “over the decades” and of drugging her.

In November, O’Connor raised concerns that she might harm herself after she posted a distressed note on her Facebook page saying she had taken an overdose in a hotel room in Ireland. The singer was later found to be safe and was taken for medical treatment.
