An Oakland Raiders player is under investigation by authorities in Pittsburgh for allegedly taunting a police dog at last weekend's game against the Steelers. 

The incident is said to have occurred in a tunnel at Heinz Field, where the K9 officer, Banditt, was patrolling for explosives.

According to WTAE in Pittsburgh, a deputy witnessed linebacker Ray-Ray Armstrong jumping, beating his chest and barking at the dog in a confrontational manner.

"The player was leaving the locker room, en route to the field, when he engaged in conduct that was very intimidating and threatening," said Allegheny County Sheriff's Office Chief Deputy Kevin Kraus.

Armstrong allegedly dared the female deputy to release the dog during the bizarre incident. 

Kraus said officers could have legally arrested Armstrong "on the spot." They've since talked to witnesses and reviewed surveillance footage, but there has been no decision on charges. 

Both Armstrong and his agent have refused to comment on the matter.

Taunting a police dog is a third-degree felony in Pennsylvania and could carry a seven-year prison sentence.

Raiders head coach Jack Del Rio reportedly called the situation "silly," doubting that police will decide to file charges.
