Chicago police advised to be on lookout for Sinead O'Connor

CHICAGO (WLS) -- An all-call was issued for Chicago police Thursday, urging officers in the city to be on the lookout for Irish singer-songwriter Sinead O'Connor after police in Ireland received a report that she may be suicidal and threatening to jump from a bridge.

"Dublin, Ireland, is saying that at 15:30 hours, Sinead O'Connor called and said, 'I'm on a bridge in Chicago and I'm going to jump,'" police said in their all-call.

Police spokesman Officer Thomas Sweeney said Thursday there isn't an active police search for O'Connor.

Around the same time the call went out, officers spotted someone threatening to jump from a bridge over a Chicago expressway, but it turned out to be a 54-year-old man. He was taken to a hospital.

Last month, O'Connor disappeared from a home in Wilmette, her friends saying she rode away on a bicycle and never returned. She was found safe at a suburban hotel.

O'Connor has used social media to call out family members overseas and it's possible she reached out to them again Thursday, leading to the call to Dublin police. Her representatives have not responded to requests for comment.
