Actor Shia LaBeouf, who was accused last week of disturbing a performance of musical Cabaret in New York, is undergoing treatment for alcoholism, his publicist said.

LaBeouf, 28, has voluntarily sought outpatient care for addiction, Melissa Kates, the former Transformers star’s spokeswoman, said in a statement.

The actor was arraigned last week on charges of disorderly conduct and harassment after police said he interrupted a performance of Cabaret inside New York’s Studio 54, used obscene language and became belligerent when asked to leave.

“He understands that these recent actions are a symptom of a larger health problem and he has taken the first of many necessary steps towards recovery,” Kates said.

A dishevelled-looking LaBeouf did not enter a plea to the New York charges, which are all misdemeanours or violations .

LaBeouf’s promising career has been upended recently by bizarre behaviour that has included attending a red carpet premiere in February wearing a brown paper bag saying ‘I am not famous anymore’.
