Nathan Heath Miller pleaded guilty to injuring police officer after RBT incident at Seaton

A man has pleaded guilty to trapping a police officer’s arm in his window while fleeing from an RBT, causing him to be flung from the car into a tree.

A man has admitted to trapping a police officer in his car window and then speeding away from a random breath test.

Nathan Heath Miller, 46, pleaded guilty in the Adelaide Magistrates Court on Wednesday to causing harm by dangerous driving and driving without due care, after the officer was flung from the car.

A prosecutor said they were withdrawing two charges, including endangering life as a result of his pleas.

Miller also pleaded guilty to failing to stop his vehicle for an alcotest, driving unauthorised and failing to answer questions by police.

During Miller’s unsuccessful bail application in May, the court heard police were performing random breath testing duties at Elaine Ave, Seaton on April 25.

They stopped a silver Holden Captiva at about 5.15pm and spoke to Miller – before requesting a breath sample.

“(Miller) said that ‘he can’t stop, he can’t stop’ and began moving his vehicle forward,” the prosecutor said.

The court heard a police officer put his hand inside the car trying to remove the keys to stop Miller from driving off.

“(Miller) then wound up the window, trapping the police officer’s arm in the window and began to drive off onto the other side of the road,” the prosecutor said.

“As he then accelerated rapidly, he wound down the window and the police officer was then flung from the vehicle into a tree and two wheelie bins on the nature strip.”

The court heard the officer suffered a broken left tibia, torn tendon to his foot, abrasions and bruising and will need surgery to repair the injuries.

The prosecutor said investigations led police to Miller’s ex-partner’s house who said he had attended there an hour prior to the incident and collected their five-year-old son.

The court heard there was a child in the back seat at the time of the incident.

The prosecutor said when Miller was arrested at Modbury North and spoken to by police he said he didn’t know who was driving the car at the time.

“Police noted that he made attempts to change his appearance, he had shaved his facial hair and shaved his head to the skin,” the prosecutor said.

“They could still see clumps of patches of unshaven hair indicating that it had been done in a hurry and recently.”

On Wednesday, Miller was committed to the District Court for arraignment in September.
