Oakland Raiders linebacker Ray-Ray Armstrong is reportedly under investigation by police in Allegheny County in Pennsylvania for, get this, allegedly taunting a police K-9. That's right. A dog. Even more stunning - taunting a police K-9 is a felony offense in Pennsylvania.

According to Rich Walsh of CBS Pittsburgh, as the Raiders were taking the field ahead of their matchup with the Pittsburgh Steelers this past weekend at Heinz Field, Armstrong "lifted up his shirt, beat his chest, and started barking and yelling at the K-9."

Allegheny County Sheriff's Office Chief Deputy Kevin Kraus offered this statement regarding the matter, via Walsh...

"We were immediately notified about the incident, and we immediately initiated a criminal investigation into the matter. Sheriff's Office supervisors interviewed witnesses and reviewed video surveillance recordings at Heinz Field. We notified the District Attorney's Office on Sunday. The Sheriff's Office is currently reviewing all of the information and reports to make a final determination relating to charges."

No word yet on the level of trauma suffered by the dog as a result of the situation, though it's probably pretty safe to say that Armstrong won't be mocking any dogs - or taking any scenic fall foliage visits to Pennsylvania - any time soon.
