Two men were in hospital last night with life-changing injuries after separate incidents which are being investigated by police.
A 20-year-old man, from Bentley, suffered a head injury and is in a coma after allegedly being deliberately run down on Sunday evening.
A driver has been charged with causing grievous bodily harm with intent following the incident.
Another man, aged 25, was badly hurt when a car ploughed into a field between Conisbrough and Old Edlington during heavy rain yesterday morning.
The incidents follow a fatality in Doncaster town centre on Sunday afternoon, also involving a young man, who was in collision with a car on Trafford Way. The 20-year-old Bentley man is understood to have been put in an induced coma by neurological experts in Sheffield after he suffered a serious head injury in the collision on Askern Road on Sunday evening.
A stretch of the A19 was sealed off for several hours after the incident while police carried out a full investigation.
It is believed to have arisen from a family party at a property in the Askern Road area and was described by a police source as ‘domestic related’.
It is understood an argument started at the partybetween the 20-year-old and a 41-year-old man from north east Lincolnshire, who is believed to be in a relationship with the younger man’s sister.
He suffered head injuries, described by police as ‘life changing’, when struck by a car on Askern Road and the driver was detained not far from the scene before being charged yesterday.
“It is alleged a silver Audi A4 was driven at the 20-year-old which is believed to have caused his injuries,” said a police spokesman.
And police were yesterday trying to establish how a car careered off the road on a country lane near Doncaster and ended up in a field near the golf course at Crookhill Park yesterday morning.
Emergency services were called to Carr Lane just after 7.30am where a silver Renault Clio had gone out of control and appeared to have left the road before ploughing into the field.
The 20-year-old woman driver escaped with minor injuries and was treated at Doncaster Royal Infirmary.
A 24-year-old man who was a passenger in the car was taken to the Northern General Hospital in Sheffield with what are believed to be serious injuries.
The road from the Five Lanes End roundabout near Old Edlington to the junction with Common Road was closed for several hours yesterday morning.
Meanwhile, police are still hoping to trace further witnesses to the fatal accident outside the railway station on Sunday afternoon.
Father-of-one Daniel Aistrop died after he was in collision with a black Audi near the pelican crossing at the junction of Trafford Way and West Street.
The driver of the car has been arrested and bailed on suspicion of causing death by dangerous driving.
* John Evans, aged 41, of Harrier Court, Grimsby, was yesterday remanded in custody by Doncaster magistrates until Tuesday, May 6, when he will appear at Sheffield Crown Court charged with inflicting grievous bodily harm with intent on the Bentley man on Askern Road.
