Body cam video shows an Ohio state trooper shouting at police not to let their dog loose on an unarmed Black man. They did it anyway.

• Body camera footage shows the moment Ohio police unleashed a dog on an unarmed Black man.
• The man, identified as Jadarrius Rose, was mauled.

Shocking body camera footage shows Ohio police unleashing a dog on an unarmed Black man, mauling him even as a state trooper warns them not to let the dog loose and shouts to get the dog off of him.

Truck driver Jadarrius Rose, 23, was attacked by the Circleville Police Department dog after he led authorities on a "lengthy" highway chase on the morning of July 4, the Ohio State Highway Patrol said.

Body camera footage recently released by Ohio state troopers shows Rose on the shoulder of US Route 23 with his hands raised in the air as a trooper with the agency calls for Rose to "come to me."

Members of the Circleville Police Department then show up with the dog and an officer tells Rose seconds later "get on the ground or you're going to get bit," according to the footage.

A state trooper nearby repeatedly warns "Do not release the dog with his hands up" just before a Circleville cop released the German Shepherd K-9 on Rose, the video shows.

"Get the dog off him!" the trooper shouts as the animal attacks Rose while he was on his knees and appeared to pull him down to the ground by his arm.

Rose loudly screams out in pain and begs over and over for officers to get the dog off him, according to the footage.

At one point as police restrain Rose, a state trooper walks in front of the body camera, covering their hands in front of their face in apparent shock as Rose screams for help.

The Ohio State Highway Patrol is leading an investigation into the pursuit of Rose and confirmed to Insider that Circleville police released the dog as "troopers were attempting to gain compliance by providing verbal commands to the suspect."

"The suspect was then taken into custody and troopers immediately provided first aid and contacted EMS to respond," the agency said.

Rose was taken to the hospital to be treated and was ultimately booked into the Ross County Jail on a charge of failure to comply with an order or signal of a police officer, records show.

The officer who unleashed the dog on Rose was identified in an Ohio State Highway Patrol case report obtained by Insider as Circleville K-9 Officer Ryan Speakman.

The case report notes Speakman "exited his patrol car and began giving commands to the suspect. Circleville K9 Officer R. Speakman deployed his K9 on the suspect."

The Circleville Police Department did not immediately respond to a request for comment by Insider.

When Rose was hospitalized following the incident, he "was upset and cursing excessively," the case report said.

"Once Jadarrius settled down, he advised he did nothing wrong and did not understand why he was being stopped," the report said.

It continued, "Jadarrius advised he was delivering in Grove City, Ohio, and just wanted to make his delivery and get home."

According to the case report, a Motor Carrier Enforcement inspector from Ohio State Highway Patrol initially attempted to stop the semi-tractor trailer Rose was driving on US 35 because it was "missing a left rear mud flap."

Rose has since been released from jail after posting bond. It wasn't clear if he had an attorney to represent him yet.
