Earlier this week we showed you the video of the Shia Labeouf beat down outside a Vancouver bar, and now we're learning Labeouf was doing more than getting owned by a shirtless fat dude.According to TMZ and Shea Carter (the flat brimmed hat bro in the video restraining the Transformers star) Labeouf allegedly made threats against the amateur rapper/good Samaritan.

LaBeouf got aggressive, spouting, "Well what if I grabbed my knife on you?"
Carter says he quickly grabbed Shia in an effort to protect himself in case the knife threat was serious.  Carter says the actor eventually walked away ... so he went back inside the bar. But moments later, Carter says, Shia appeared outside a window and made a throat-slashing gesture at him ... before leaving for the night.

I would say I'm surprised, but after a couple years on the Evansville bar scene, you get a little desensitized to these things.
