Four football fans remain in hospital after a car ploughed into them as they waited to cheer on their team ahead of the weekend’s NRL grand final.

P-plater Indika Bambrick Samarasinghe, 18, was allegedly behind the wheel of a BMW when it careered into a crowd gathered by a roundabout at Wallsend, near Newcastle, on Saturday morning.

The crowd was waiting to farewell the Newcastle Knights on their journey to Sydney to play in the NRL grand final, which they narrowly lost to the Roosters on Sunday.

The incident left 10 people in hospital, including a five-year-old girl who was initially in a critical condition.

On Monday, NSW Health said six of the patients had been discharged, with three still in hospital in a stable condition.

One patient, understood to be the young girl, is now in a serious but stable condition.

Samarasinghe faced court on Sunday after being charged over the incident. He did not apply to be released from custody and was formally refused bail.

Among those injured was Chris Clancy, who said there was a carnival atmosphere at the roundabout with cars beeping their horns and people waving before the disaster unfolded.

“The next thing, this car stops [at] the roundabout and then he just floored it on the wet ground, lost it,” he said.

“It happened in seconds, but when you stand there, seeing the car coming at you, I honestly thought I was going to die. It just felt like slow motion.”

Clancy suffered fractures in his ribs, spine and foot, and a broken collarbone. He wrote on Instagram on Monday that surgery for his collarbone had been postponed until Tuesday.

“Everything is going fine, still a bit sore but I’ll get there,” he wrote.

Investigators did not believe the incident was deliberate but previously declined to comment on reports the vehicle was being driven erratically before the crash.

Samarasinghe was taken to hospital for mandatory testing and subsequently charged with nine offences, including dangerous driving occasioning grievous bodily harm, negligent driving and causing bodily harm by misconduct.

The bail court was told the most serious offence of dangerous driving occasioning grievous bodily harm carried a maximum jail term of seven years.

Samarasinghe will next appear at Newcastle Local Court on October 15.

The Knights lost the final to the Sydney Roosters by just a point.
