Chicago police are searching for singer Sinead O'Connor, who left for a bike ride at 6 a.m. on Sunday and has not returned, the Chicago Tribune reports.
"A caller has expressed concern for her well-being, and no other information is available at this time," police said in a statement. The singer was last seen wearing a black parka, black leather pants, a sweatshirt that said "Ireland" on the back, and was riding a motorized bike with a pink basket. Police were notified at about 1 p.m. on Sunday, and TMZ reports that O'Connor is being classified as "missing suicidal."
"Officers conducted checks of the area in which she was last observed, including parks and beaches," police told the Tribune.
This news comes a week after Arsenio Hall sued O'Connor for defamation for claiming that he contributed to Prince's death.
