Masters champion and world number one Scottie Scheffler, who is five shots back of overnight leader Xander Schauffele, is scheduled to tee off at 10:08 am ET (15:11 GMT) after being detained by police for an incident unrelated to the accident.

No further details about the nature of the accident near Valhalla were provided by officials but ESPN, citing a police spokesperson, said a shuttle bus struck and killed a pedestrian outside the club.

According to the ESPN report, Scheffler was detained in handcuffs after a misunderstanding with traffic flow led to his attempt to drive past a police officer into the entrance at Valhalla ahead of the second round.

The ESPN report also said a police officer attempted to attach himself to Scheffler's car and then the Masters champion stopped his vehicle at the entrance to Valhalla.

According to the report, the police officer then yelled at Scheffler to get out of the car, and when he did shoved the golfer against the vehicle and placed him in handcuffs.

A video posted online that was not verified by Reuters shows one police officer leading Scheffler to a police car while another says to a camera: "Right now, he's going to jail, he's going to jail and there ain't nothing you can do about it. Period."
