ESPN reporter Jeff Darlington, who witnessed the incident, said on air: “Traffic had been backed up and building, Scottie Scheffler tried to enter Valhalla Golf Club using a side median, at which point a police officer instructed him to stop.

“Scheffler attempted to continue to go, the police officer then attached himself to the side of Scheffler’s car.

“Scheffler stopped the vehicle as he turned into Valhalla Golf Club at the entrance, about 10 to 20 yards from the point at which the police officer first told him to stop.

“At that point the police officer instructed Scheffler to get out of the car.

“He rolled down the window, the police officer grabbed his arm and started pulling at it. He reached inside, opened the car door, pulled Scheffler out, pushed him up against the car, immediately placed him in handcuffs.”

LMPD had earlier released a statement on the traffic accident.
