Raiders LB under investigation for allegedly taunting service dog before game

Oakland Raiders linebacker Ray-Ray Armstrong is reportedly under investigation by the Allegheny County Sheriff's Office in Pittsburgh after allegedly taunting a K-9 service dog before a game against the Steelers on Sunday at Heinz Field.

According to ESPN, the alleged crime is a third-degree felony in Pennsylvania and charges could be brought against Armstrong by the end of the week.

Armstrong apparently barked at the dog while lifting his shirt and pounding his chest between leaving the locker room for the field during warmups, chief deputy Kevin Kraus said.

"The dog was going crazy," Kraus said. "The deputy was trying to control the dog the best she could."

The sheriff's office did not speak with Armstrong before the team left Pittsburgh, but it has informed the Steelers, the NFL and the Raiders an investigation is being carried out that includes interviews and review of surveillance cameras.

The two teams and the NFL refused to comment on the situation.
