Shia LaBeouf was involved in a fight outside of the Cinema Public House in Vancouver, Canada, marking the latest in a growing list of alcohol-related incidents for the 25-year-old 'Transformers' star.

According to an eyewitness, LaBeouf began scuffling with another inebriated patron inside of the bar after that man had "said something stupid" to the actor. Security tossed both combatants out, and the fight escalated in the street.

Footage obtained by TMZ shows a shirtless man pummeling LaBeouf, as he lay defenseless on the curb. Once others began to intervene, the shirtless man fled the scene.

LeBeouf was briefly detained after another bar fight earlier this year in Sherman Oaks, CA. In 2008, the actor's license was suspended for a year when he refused a Breathalyzer after being involved in car accident. In 2007, LaBeouf was arrested after refusing to leave a Chicago-area Walgreens.
