A POLICE officer who rammed into a fleeing offender's vehicle during a high-speed pursuit has pleaded not guilty to reckless conduct.

Leading Sen-Constable Brett McCormick, 38, was behind the wheel of a marked police vehicle with his lights flashing on Wellington Rd, Mulgrave when he executed a U-turn and crashed into an oncoming Commodore driven by Aaron Vilbro in January 2012.

Vilbro, who later told police he had been recently released from jail, had failed to stop when an unmarked police SS station wagon driven by Sgt Dean Pickering tried to intercept him for speeding and gave chase from Wheelers Hill, a County Court jury heard yesterday.

Video evidence from a camera in Sgt Pickering's vehicle of the subsequent pursuit was shown in court and depicted Vilbro's Commodore speeding and continually crossing to the wrong side of the road.

Sgt Pickereing used his police radio to update D24 and a pursuit controller as the chase continued and Sen-Constable McCormick positioned his vehicle in Wellington Rd to prepare to take over the pursuit, the court heard.

As the Commodore entered Wellington off Springvale Rd it accelerated and then slowed and Sen-Constable McCormick's police sedan collided with the right-hand side of Vilbro's vehicle, the jury heard.

The court was told police had no policy of ramming cars in order to end a pursuit.

When arrested, Vilbro was asked about endangering other drivers and said "it's not my problem", the court was told.

Amphetamines and a scale were found in Vilbro's vehicle and he was charged with a range of traffic offences and later pleaded guilty to evading police, the court heard.

Defence lawyer Geoffrey Steward said it was "totally rejected and denied by the defence the allegation that Brett McCormick deliberately drove into the car driven by Aaron Vilbro ... although Vilbro was driving in a reckless, dangerous and hoon-like manner."

But prosecutor Bill Stougiannos said the Crown alleged "this ramming of the vehicle was an unreasonable act on his (McCormick's) part, an unnecessary action, an unlawful action."

Sen-Constable McCormick yesterday pleaded not guilty to reckless conduct that may have placed others in danger of serious injury.

The trial, before Judge Sue Pullen continues.
