Sinead O’Connor, the Irish singer-songwriter, has been reported missing after going on a bike ride on Sunday.

Sinead O’Connor Missing

Police in Wilmette, Ill., released a statement Monday to confirm that O’Connor’s whereabouts are currently unknown, and that they were tipped off to her diappearance from a caller who was concerned about the singer.

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

O’Connor was riding a Raleigh motorized bicycle with a pink basket, and was wearing black leather pants, a black parka and a sweatshirt that was emblazoned with “Ireland” on the back, according to an alert obtained by TMZ.

Possibly adding to the concern regarding O’Connor’s whereabouts is the last post on her Facebook page, which appears to be directed at her eldest son Jake Reynolds.

“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,” O’Connor wrote. “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.”

O’Connor had received medical treatment back in November after posting on Facebook that she had taken an “overdose” in an apparent suicide attempt.
