Alleged SA victim denies being a VIP

A prominent Adelaide businessman who says he was assaulted by a police officer has denied his initial gripe was that he was not being respected as "a very important person".

Yasser Shahin, 38, has told a Supreme Court jury of being grabbed by the shoulder, pushed and bullied after he was pulled over because the tinted windows on his Rolls Royce were too dark.

Constable Norman Hoy, 59, has pleaded not guilty in the District Court to the aggravated assault of Mr Shahin, whose family owns Peregrine Corporation, Shahin Enterprises, BP On the Run, Smokemart and the SA outlets of Krispy Kreme.

Mr Shahin had his wife, mother and baby son in his car when he was pulled over in Grenfell Street in the CBD on September 18, 2010.

Hoy was wearing a personal recording device which captured most of the incident and which will be played to the jury.

During her cross-examination on Thursday, defence lawyer Marie Shaw, QC, referred Mr Shahin to the time of the incident, not afterwards when he had spoken to various police commissioners and inspectors.

"At the time of the audio, when this event was occurring, your major complaint with Mr Hoy was that he had bad manners, he wasn't respecting you as a lawyer, as a very important person," she said.

"Wasn't that your real gripe with Mr Hoy at the time?"

Mr Shahin replied: "Not at all", saying "I don't think I am any more important than anyone else".

Ms Shaw asked the businessman a number of questions referring to various statements he had made about the incident.

"I would challenge anyone, after a 12-minute altercation with a police officer to remember every word and the manner in which it was said and the order in which it was said," Mr Shahin said.

"That's an unreasonable, unrealistic standard to hold me to, and to suggest I have been untruthful and withheld something because the sequence of the exact words doesn't match is extraordinary and very unfair."

Ms Shaw asked him about his use of the word "handled" when telling the jury what Hoy had done.

"I was handled, touched, pushed, grabbed and dragged almost, pushed back and I have used the word handled as the best term to describe it."

The trial is continuing.
