CHICAGO — Chicago Police issued an all-call radio message telling officers to look out for Irish singer Sinead O'Connor after an apparent suicide threat Thursday.

Around 5:30 p.m. and again about an hour later, the message was relayed over multiple police radio frequencies, reporting a call from police in Dublin that "Sinead O'Connor called and said 'I'm on a bridge in Chicago and I'm going to jump,' if officers could keep an eye out for the celebrity."

Police officials confirmed the alert Thursday evening. Officers were still looking for O'Connor as of Friday morning, said spokeswoman Laura Amezaga, though O'Connor denied she had "jumped off a bridge" in a post on Facebook early Friday.

Reports of a suicide threat were "false and malicious gossip," O'Connor wrote.

Last month, O'Connor was found safe after she was reported missing in suburban Wilmette.
