Irish singer Sinéad O'Connor has been found safe, report The Guardian, after going missing for a day in a Chicago suburb. 

Last seen going on a bike ride on Sunday morning around 6am in the Chicago suburb Wilmette, wearing black leather pants, a black parka and a sweatshirt reading “Ireland”, O'Connor was on a Raleigh motorized bike with a pink basket.

The singer has previously publicly suffered with her mental health and with problems over the custody of her four children, posting a message to Facebook last November in which she stated she had taken an overdose of pills as a result of her family’s “cruelty”. She was later found safe.

A caller who reported O'Connor as missing on Sunday morning “expressed concern for her well-being” when she didn't return from the bike ride, while TMZ are reporting that an alert sent out by police classifies O’Connor as “missing suicidal.”

Following a long custody battle with her ex, Irish musician Donal Lunny, for their 12-year-old son Shane, O’Conner, aged 49, once again took to Facebook to write about the problem, this time addressing recent involvement of “Jake,” who appears to be her 28-year old 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,” 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.”

The organization Tusla mentioned above is a child and family agency in Ireland.

O'Connor also changed her profile picture on the social media site to that of a wired cage in the shape of a woman kneeling on the ground that is filled with rocks shortly after the post.

Her son Jake Reynolds was cited as the reason for her despair last November when the singer wrote that he and his girlfriend had made her the victim of “appalling cruelty.” Reynolds is the father of O'Connor's only grandchild.

On May 13, O'Connor wrote a letter to her son Shane via Facebook in which she advised him to get his own solicitor so he could leave Tusla, as any contact she had with them made her unwell again. In the letter she claimed that she was being bullied by the agency and that her son wished to return to her but his wishes were being denied.

She pleaded with the 12-year-old to find a lawyer and say he wanted to leave Tesla, insisting that he ask to be with his brother Jake if he couldn’t be with her.
