Shia LaBeouf is due to appear in court later this month

Police were called after a security guard told Mr LaBeouf to leave a branch of the Walgreens drug store because he seemed to be drunk.

Police spokeswoman Laura Kubiak said the 21-year-old actor was "very courteous and polite".

He is due to face a misdemeanour criminal trespass charge in Cook County court on 28 November.

The Transformers star was not breathalysed as he had not been driving.

The actor is set to co-star with Harrison Ford in Indiana Jones and the Kingdom of the Crystal Skull, which is due to be released next year.
