Three Chinese nationals in Kenya have been charged in connection with a corruption scandal involving the recently-built railway between the coastal city of Mombasa and the capital, Nairobi.
They are are accused of offering investigators a bribe of around $5,000 (£3,900) during an investigation into a ticketing scam.
This is the latest controversy over the project which was paid for with a Chinese loan of more than $3bn.
Critics said it was too expensive and questioned a decision to use diesel locomotives.
Two senior Kenyan officials were charged in August over allegations they made more than $2m by falsifying compensation claims for the land to build the Chinese-operated railway.
