Alec Baldwin was examined at a hospital after his daughter called authorities from their Manhattan apartment, a US law enforcement official said.
The official, who spoke on condition of anonymity because they were not authorised to speak publicly, said the 30 Rock actor and his young daughter had argued and she told authorities he had threatened to take pills.
Baldwin's publicist issued a statement calling it "a misunderstanding on one person's part".
The statement said the Hollywood star was "quickly released", is "completely fine and will be at work" today.
In 2008, Baldwin blamed a bitter custody battle with ex-wife Kim Basinger in part for the stress he was feeling when he berated their daughter, Ireland, in a phone message.Reuse content
