According to TMZ.com, the California Highway Patrol officer who arrested Cardinals linebacker Joey Porter is reportedly under investigation for police brutality.

As we previously reported, the Arizona Cardinals linebacker was busted during a traffic stop at a Taco Bell in Bakersfield, CA over the weekend.

Porter was busted for allegedly slapping the deputy’s hand away as the deputy tried to unlock Joey’s car door. Joey claims the deputy manhandled him, striking him in the face.

Now we’ve learned CHP has launched an Internal Affairs investigation into the deputy’s conduct.

I don’t envy what police officers have to do in order to protect themselves on the job. But if this cop really drew his gun because Porter slapped his hand, then that’s a little absurd.

We’ll have to wait for more details to emerge.
