Taxi driver Ilias ‘Lou’ Bougias was happening to pass by the Eastern Freeway on Wednesday afternoon driving a passenger to their destination, when he heard the sounds of the horrific crash that led to the single greatest loss of life in Victoria Police history.

The 49-year-old Greek Australian saw devastation unfolding before his eyes, just like in January 2017 when he happened to be at the scene of one of the biggest tragedies in recent Australian history, the Bourke St rampage.

Back then, Mr Bougias was hailed as a ‘genuine hero’ for providing first aid to Jim Gargasoulas’ pedestrian victims, but this time he was not destined to help save anyone.

He immediately pulled over to the emergency lane and rushed to assist.

Βut the three male police officers Constable Josh Prestney, Constable Glen Humphris and Senior Constable Kevin King had been killed instantly from the collision and Leading Senior Constable Lynette Taylor, the female officer of the group, also eventually succumbed to her severe injuries.

“It was mayhem – something I never want to see again,” Mr. Bougias said speaking to The Age on Friday.

The spectacle, he said, was “worse than Bourke Street” because of the injuries suffered by the four police “killed within a twenty-metre radius.”

The officers died after being hit by a truck while at the emergency lane of a routine traffic stop. They were prepared to impound a Porsche that had been pulled over for allegedly speeding with the driver’s drug test allegedly returning positive.

Mr Bougias, who was missed being hit by pure luck, said he saw the semi-trailer truck crossing three lanes of traffic before landing on the emergency lane and hitting the two police cars and the luxury vehicle.

The Porsche driver was reportedly on the side of the road urinating and left the scene unharmed. On Thursday he was taken into police custody while the truck driver has been hospitalised guarded by police.

“My eyes go straight to the rear vision mirror and I saw it all behind me,” he said.

“The [police] station wagon flew across four lanes, how it didn’t kill anybody else was amazing. The debris was going past me. The car missed me by about 20 metres.”

Following the incident, Mr Bougias went to the Boorondara Police Station to provide a witness statement.
