"The Wilmette Police is seeking to check the well-being of Sinead O'Connor," the police department told Billboard in a statement. "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 has recently made news for alleging that Arsenio Hall gave Prince drugs over the years. Hall hit back with a $5 million lawsuit for defamation.

The singer has also had a history of mental health issues, including a misdiagnosed bipolar disorder, PTSD and depression. O'Connor had a suicide scare last year after family issues became public. In 2013, she opened up to Fuse about her mental health:
