A man jailed at the same time as world No.1 golfer Scottie Scheffler says he had no idea he was behind bars with the champion until a police officer told him.

The comments came as further details emerged in Scheffler’s shock arrest early last Friday, as he was driving into Louisville’s Valhalla Golf Club for the second round of the US PGA Championship.

There was heavy traffic at the time because a pedestrian had been struck and killed by a shuttle bus.

Scheffler was stopped by Detective Bryan Gillis, who – according to a police report – “attempted to give instruction”.

The golfer is accused of refusing to comply, and instead “accelerated forward, dragging Detective Gillis to the ground”.

Gillis was rushed to hospital while Scheffler was arrested. He has been charged with second-degree assault of a police officer, third-degree criminal mischief, reckless driving and disregarding traffic signals from an officer directing traffic.

He is expected to face a Louisville court on Tuesday, where there are multiple media reports that his charges may be dropped.

The golf champion’s stint in jail was brief. He was arrested about 6am but released in time to make his 10am tee-off at Valhalla.

On Monday (Australian time), a man who was also in custody at the same time told TMZ that Scheffler repeatedly said his arrest was “bulls–t”, although he didn’t seem particularly aggressive.

The same man said he did not recognise Scheffler until an officer told him who he was.

“You know you’re talking to the No.1 golfer in the world, right?” the inmate was reportedly told.

Scheffler reportedly drew quite a crowd during his time in custody, with officers and jail staff lining up to see him and ponder how long he would be there.

Scheffler to face court

Scheffler has told ESPN reporter Jeff Darlington he was “proceeding as directed” by officers when the incident occurred.

“It was a very chaotic situation, understandably. So considering the tragic accident that had occurred earlier, and there was a big misunderstanding of what I thought I was being asked to do,” he said.

“I never intended to disregard any of the instructions.”

Recent reports suggest the charges against Scheffler may be dropped. His lawyer Steve Romines insists the golfer is otherwise prepared to go to trial .

Romines said officers outside the Valhalla Golf Club were “advising different things”, which led to a miscommunication.

“Scottie was advised by one officer to go around and turn left into the facility,” he told the Golf Channel over the weekend.

“But the officer who charged him obviously didn’t know that. So, that’s where the miscommunication occurred.”

Scheffler carded a closing 65 at Valhalla on Sunday to share the early clubhouse lead on 13 under par.

But his chances of claiming back-to-back major titles effectively ended with a third round of 73.

He eventually wounded up equal eighth and exhausted.

“I’m trying to figure out how quickly I can get home from here and, yeah, that’s pretty much it. I think I’m just fairly tired and ready to get home,” Scheffler said.

Californian golfer Xander Schauffele won the title.
