O'Connor is said to be in Chicago, but no one is sure of her whereabouts.
Chicago police are on the lookout for Sinead O’Connor after the singer threatened suicide on Thursday, PEOPLE has learned.
Following a call that came in around 5:30 p.m. local time from Dublin police in Ireland, CPD “issued an all-call radio message,” alerting officers to keep their eyes peeled for the Irish singer, according to DNA Info.
“Sinead O’Connor called and said, ‘I’m on a bridge in Chicago and I’m going to jump,'” Irish authorities reportedly told Chicago police, as they asked the department to keep a watchful eye.
Police would not confirm the call was specifically for O’Connor.
This comes one month after O’Connor disappeared in Wilmette, a Chicago suburb.
In mid-May, the 49-year-old failed to return from an early morning bike ride and was classified as “missing suicidal.”
Last year, O’Connor was found safe in Dublin after penning a suicide note on Facebook, saying that she’d taken an overdose. Police had visited her at least one time before in 2011 after she reportedly sent a string of suicidal tweets.
