Sinead O’Connor reported missing

Sinead O’Connor is missing.

The 49-year-old singer was reported missing in Illinois after going for a bike ride at 6am on Sunday (05.15.16) and not returning.

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

Wilmette Police Chief Brian King said Sinead was riding a Raleigh motoriZed bicycle with a pink basket, and was last seen wearing a black parka, black leather pants and a sweatshirt with ‘Ireland’ written on it.

Before she disappeared on Sunday, Sinead posted a message online directed at her oldest son Jake Reynolds about her other son Shane, 12, who has been placed with TULSA child services agency in Ireland.

She wrote: "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,’ wrote O’Connor.

"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 (sic)."

The Donal she refers to is believed to be Shane’s father Donal Lunny.

And just days before that, she posted an emotional message to Shane, which read: "Baby, I’ve been trying to get you out of care but Tusla are being monsters. I have to back off because they are hurting me so badly I get unwell again if I go near them.’

"The best thing I can do is advise you get a solicitor of your own which you are now entitled to because you are 12 and bring a case of your own against Tusla, under the Children’s rights clauses of the constitution (sic)."

Last year Sinead caused concern after claiming she took an overdose.

The ‘Nothing Compares 2 U’ singer – who underwent a hysterectomy in August – posted a worrying message on Facebook claiming she had checked into a hotel in Ireland under a different name and had overdosed.

The star told how she had been "howling, crying for weeks" and insisted she "doesn’t matter a shred to anyone" and that her family wouldn’t notice for weeks if she ended her life.

However, police rushed to her aid and she was given medical assistance.
