A van driver deliberately mowed down a man, sending him flying, after being confronted about his bullying of a newly qualified motorist.

John Newlands was following 29-year-old Kylie Stewart - who had only passed her test three months earlier - on the A90 on the outskirts of Dundee when her car stalled.

Newlands sounded his horn before tailgating Ms Stewart down the Kingsway dual carriageway and overtaking her.

As they approached a roundabout, her partner, Ronald Lothian, 41, got out to remonstrate with Newlands.

CCTV footage screened at Dundee Sheriff Court on Tuesday showed Mr Lothian approach Newlands' van to tell him he was going to report him to police.

Fiscal depute Eilidh Robertson said: "A struggle then ensued between the men whilst the accused [Newlands] was still sitting in the driver's seat and the complainer [Mr Lothian] was standing next to him outside, with them both grappling with each other.

"Mr Lothian then walked a short distance away from the accused's van before stopping and standing on the carriageway whilst still facing the accused's van.

"At this stage the accused drove his van towards Mr Lothian, striking him on the body and propelling him into the air before he landed on the central reservation."

Mr Lothian suffered only minor injuries and managed to get up and give chase as Newlands drove off, weaving through traffic and running a red light.

Newlands, 47, a prisoner at HMP Perth, pleaded guilty to assault on Kingsway, Dundee, on July 10, last year.

Sheriff Alastair Carmichael jailed Newlands for two years, reduced from three years for his early guilty plea.

Sheriff Carmichael said: "It seems to me that this was a moment of madness on your part.

"It seems to have stemmed bizarrely from the complainer's girlfriend stalling her car.

"That was followed by some questionable driving on your part.

"It was ended by you driving a van at the complainer and hitting him.

"He was bounced off and propelled into the central reservation.

"Amazingly, he suffered only minor injuries but your actions were irresponsible, inherently dangerous and had the potential to cause untold damage."
