Shia LeBeouf Threatened To 'Pull A Knife' On Attacker

Shia LaBeouf allegedly threatened to "pull a knife" on the man who tried to calm him down after his bar bust-up in Vancouver earlier this week.

The Transformers actor never produced a blade, but according to Shea Carter - the man who helped calm the situation down, LeBeouf was furious and threatened him.

Carter, a local hip-hop artist and a regular at the Cinema Public House, told TMZ that he'd seen the actor acting drunk in the bar before the fight and noticed him bumping into people, with one man saying: "Hey man, watch out."

Carter claims that Shia had responded: "Oh yea? Or what? What are you going to do about it?" This is when the two decided to take their beef outside, and Shia was beaten to the floor.

Once Carter tried to diffuse the situation, and stop Shia from going back into the bar, the actor allegedly said: "Well what if I grabbed my knife on you?"

That's when Carter grabbed the actor to make sure that the knife threat was not a serious one. Shia decided to walk away from the scene, so Carter went to continue his night back in the bar.

But the Transformer actor reappeared and even made a few throat-slashing gestures before disappearing again.
