Young actor Shia LaBeouf had an eventful weekend, as he was arrested in downtown Chicago early Sunday after he allegedly refused to leave a Walgreens store.

Shia LaBeouf was arrested in the very early hours of Sunday morning outside a Walgreens in downtown Chicago after being told repeatedly to leave the store. TMZ.com has the inside scoop and reports that Shia refused to attend a security guard’s request to leave.

Chicago police told the website that that the arrest occurred at around 2:30 AM; the 21-year-old actor allegedly appeared drunk to the store’s security guard. He detained the actor and called police.

This apparently did not prevent Shia from being “very courteous and polite” with the police. The Los Angeles Times reports that he was taken to the Near North police district, quoting Chicago police spokesman Marcel Bright.

He posted bond before 7:00 AM that same day. He was charged with misdemeanor criminal trespassing and is scheduled to appear in court on November 28.

Shia starred this year in the teen thriller “Disturbia,” alongside Carrie-Anne Moss, David Morse and Sarah Roemer. The film, described as a teen version of the Hitchcock classic “Rear Window,” opened at No. 1 in the North American box office.

Shia also appeared in “Transformers,” based on the Transformers franchise, alongside Josh Duhamel, Megan Fox, and Jon Voight.

The young actor, who came to fame on the Disney Channel’s “Even Stevens,” next appears in the fourth Indiana Jones installment, “Indiana Jones and the Kingdom of the Crystal Skull,” starring Harrison Ford as heroic archeologist Indiana Jones.

Cate Blanchett, Ray Winstone, John Hurt and Jim Broadbent are also part of the cast, while Karen Allen returns as Marion Ravenwood, Indy’s love interest and ally in 1981’s “Raiders of the Lost Ark.” Sean Connery will not reprise his role as Indy’s father in the fourth installment.

“The Kingdom of the Crystal Skull” is slated for a May 2008 release, nearly 19 years after the third installment, 1989’s “Indiana Jones and the Last Crusade.”
