Marshawn Lynch was dragged out of his car by the hood of his sweatshirt and forcibly thrown to the ground during his DUI arrest earlier this week ... new police video shows.

In the footage, which was captured shortly after cops had begun questioning the former NFL star on Aug. 9 in Las Vegas, you can see Lynch was leaned back in the driver's seat of a 2020 Shelby GT500 -- appearing to be uncooperative with cops who were asking him to get out of the ride.

The officers can be heard in the video asking Lynch repeatedly to step out of the car -- but Lynch refused continuously, asking over and over again why he had to leave the vehicle.

After officers told him he was "obstructing an investigation," one of the cops reached in and grabbed him by the orange sweatshirt he was wearing.

The cop then threw the ex-Seattle Seahawks running back on the ground ... and told him, "Roll over. Hands behind your back. No more games today."

Officers then can be heard on the video saying he smelled like alcohol.

In police documents, obtained by TMZ Sports, cops say when they got Lynch back to the station, he was uncooperative there -- and said they "had to use a restraint chair" to draw blood from him after obtaining a search warrant.

Lynch was ultimately booked on several charges, including DUI. He's due in court for a hearing on the matter in December.

The 36-year-old's attorneys, Richard A. Schonfeld and David Z. Chesnoff, released a statement on the matter Thursday afternoon ... saying, "Marshawn was not pulled over for a DUI. Rather the vehicle was safely parked and not in operation. We are confident that when all evidence is presented, this will not be a DUI under Nevada law. Marshawn appreciates and is thankful for everyone’s concern and support."
