A British motorcyclist was killed in a fiery smash after a stolen BMW crashed into his bike and dragged him down the road.
Keith Stevens, 33, originally from Forfar, Scotland, but now living in Melbourne, was riding home from work when he was hit.
Mr Stevens, a sheet metal worker with a young son, was rushed to hospital but died of catastrophic injuries including burns to 50 per cent of his body.
Four teenagers have been arrested and charged in connection with the hit and run and and also face a string of car theft charges.
Mr Stevens' family have paid tribute to him in a statement released by police in Australia and told how his organs were donated to help save other lives.
They said: 'Keith was a loving father, partner and son. We will remain forever devastated by his loss.
'His passing in the most tragic of circumstances has left us all with immense grief and overwhelming sadness.
'Born in Scotland, he called Australia home. His death is being felt by the lives he touched around the world.
'Keith was our gentle giant and he leaves behind shocked friends and family.
'Keith was an organ donor and we know he would be pleased that in these most tragic of circumstances he was able to help improve the quality of others' lives.
Mr Stevens had lived in Australia for 10 years and was killed on November 9.
An online campaign raised more than £3,000 to help his relatives travel to Australia for a memorial service and friends have taken to social media to pay tribute to him.
Police allege the four teenagers in the car left the crash scene, dumped the BMW and then robbed a nearby home, stealing a Toyota.
A 17-year-old boy, accused of driving the BMW, has been charged with culpable driving and aggravated burglary.
Another 17-year-old is facing charges of aggravated burglary, four counts of theft of motor vehicle, attempted home invasion and home invasion. Two 18-year-olds are also facing burglary and home invasion charges.
Police have said they are not looking for anyone else in relation to Mr Stevens' death.
