London - Shia LaBeouf has been arrested for disorderly conduct and criminal trespass.
The troubled actor was handcuffed and escorted out of a Broadway performance of 'Cabaret' on Thursday after he reportedly began yelling erratically and slapping people's backsides.
A NYPD spokesperson told Us Weekly: "[Shia] has been charged with disorderly conduct. He was also charged with criminal trespass. While at Studio 54 he was upsetting patrons, being loud and yelling. He'll be jailed. There will be a court appearance for this matter."
An eye-witness added to the publication: "Shia seemed out of sorts. He was interacting with strangers during the show and slapping peoples' backsides. He was trying to avoid the police and fell. Then he was cursing at the police while being taken into custody."
The 28-year-old actor - who has sparked fears for his mental health in recent months - reportedly had tears in his eyes as he was led out of the New York City musical, which stars Michelle Williams and Alan Cumming, during the intermission.
Another source revealed that the 'Transformers' star was "harassing audience members, harassing actors on the stage, and chain smoking inside the theater."
The bizarre incident comes after Shia declared he intended to retire from acting and "all public life" following "attacks against his artistic integrity".
The star has had a difficult few months, culminating in him storming out of a 'Nymphomaniac' press conference in Berlin before arriving on the red carpet for the film's German premiere wearing a paper bag on his head that read, "I am not famous anymore."
He was also forced to apologise for alleged plagiarism and starred in his own silent art installation in Los Angeles.
Meanwhile, stars including 'Girls' creator Lena Dunham have been reacting to the news on Twitter.
She joked: "I feel you Shia: In 1993 I was carried out of Les Mis screaming because I couldn't handle the intimations of death.
