Keven Drew De Vroom, 47, was charged with serious assault and stealing after he was accused of kicking and hitting police officer David Nelson at Balmoral Ridge in the Sunshine Coast Hinterland in December 2017.

Senior Sergeant Nelson told the District Court trial in Maroochydore this week that he stopped De Vroom after recording him driving at 121kph in a 70 zone along Maleny-Montville Road.

The pair then got into a physical altercation, leaving Snr Sgt Nelson with soft tissue injuries and fractured teeth.

De Vroom maintained he was "absolutely not guilty" of the charges, and was instead the victim of police brutality in an unprovoked attack.

Crown Prosecutor Alex Stark told the court Snr Sgt Nelson had simply been carrying out his policing duties and was met with an aggressive and uncooperative De Vroom who brutally assaulted him, including choking and kicking him in the head.

On Friday, a Sunshine Coast jury found De Vroom guilty of both charges.

Throughout the three day trial, the court was shown recordings from a police helmet and the defendant's phone where Snr Sgt Nelson can be seen approaching De Vroom's white van and asking him to produce identification.

De Vroom told the officer "I don't have to give you any identification, don't order me mate, I don't consent to this".

He added "I'm under duress and threat of menace" and can later be heard yelling "that's break and enter".

When giving evidence, Snr Sgt Nelson told the court he had attempted to open De Vroom's car door to remove the keys when the accused slammed the door on his arm, kicked him in the head several times, choked him, and eventually sped off in his van.

He said he feared for his life during the attack, could not breathe, and thought "this is how I'm going to go".

The court heard the officer's police helmet was later located in a garbage bin at the defendant's property, relating to the stealing charge.

Defendant claims officer attacked him

While giving his own testimony, De Vroom said he did not know why he had been pulled over by the officer and said he does not give out such identifying details "to strangers".

He said Snr Sgt Nelson lashed out, wrenched his car door open, and attacked him without reason.

"I tried to hold the door closed with all my might. I said 'this is break and enter get out'. I was pushed and punched," he told the court.

"After that I yelled 'how dare you attack me. When you settle down I will release you'. I slammed the door shut and said 'leave me the F alone'.

De Vroom said he fled the scene "in fear".

Mr Stark suggested De Vroom was lying about the incident and had used a "bizarre, pseudo legal philosophy" to support his own fictional story line.

He told the court De Vroom was an "irrational, arrogant, and self-righteous" person who did not like police and felt above the law.

De Vroom replied "I don't like police that act above and beyond their duty in a cowardly manner".

Witness saw man kicking at officer

Throughout the trial, the court heard from a number of witnesses, including onlookers and police who later attended the scene.

Sunshine Coast Council environmental officer Dean West gave evidence during the trial, telling the court he had been driving on the opposite side of the road on the day of the incident and saw a man kicking at a police officer out of a van.

"I slowed down and noticed a police officer standing at a white van inside the door, some legs were projecting from inside of the van toward the officer and kicking out," he said.

"[The person] was kicking his [police officer's] upper body and toward his head.

"I also saw some hands coming out of the van toward the officer again."

In closing submissions, Mr Stark said De Vroom had been an unreliable, hot-headed conspiracy-theorist whose temper had been witnessed in the provided videos.

De Vroom's defence barrister Scott Lynch said Snr Sgt Nelson's evidence was simply "well-rehearsed" and did not align with the injuries he endured.

But after more than three hours of deliberation and having considered both submissions, the jury found De Vroom guilty of both serious assault and stealing.

De Vroom was remanded in custody and is due to be sentenced next Thursday.
