A Cambodian man who found he had no money with him when buying petrol ended up paying with his nephew, local media has reported.
The man was on a road trip with nine-year-old Dy, searching for the boy's father, when their motorbike ran out of fuel.
The boy's uncle filled up the bike with three litres of petrol at a roadside stall before realising that he had forgotten his wallet, the Kampuchea Thmey (New Cambodia) newspaper said.
He succeeded in convincing the old woman who sold him the petrol to take his nephew as a deposit while he went off to get the $1.50 he owed.
But he never returned. Nearly two years on, the petrol vendor has decided to keep the boy.
"I have decided to take care of him and raise him as my own
grandson," she told the paper.
In Cambodia, where more than half of the population is under 18 years of age, the rights of children remain weak.
Human trafficking and exploitation remains a major problem in a country which is still rebuilding after decades of civil war.
