Fears for her safety had been raised when she had failed to return and police received a call from someone concerned about her wellbeing.
O’Connor, 49, was seen at 6am on Sunday when she left the Chicago suburb of Wilmette on a Raleigh motorised bicycle with a pink basket, wearing black parka, black leather pants, and a sweatshirt with ‘Ireland’ on the back.
Wilmette police subsequently issued a statement saying they were “seeking to check the well-being of Sinead O’Connor”.
According to TMZ, investigators classified O’Connor’s disappearance as “missing suicidal”, though police would not comment.
O’Connor has a history of mental health issues and is known to have been going through family problems over the past year. She left a note in November in which she said she had taken an overdose of pills at a hotel in Ireland, blaming her family for “betrayals”, but she was later found safe and received medical attention.
O’Connor also previously spoke of a suicide attempt on her 33rd birthday in 1999.
By 6.30pm Irish time yesterday, more than 200 calls had been made to the Wilmette Police Dept in relation to Sinéad O’Connor.
Last night, the police issued a brief update saying the singer had been located. “She is safe and is no longer listed as a missing or endangered person,” the statement said.
