The government driver who tipped off municipal councillors said he had no regrets despite being discriminated against after exposing the saga.
Lo Pui-lam, 54, who has been with the civil service for 16 years, also said the scandal was much bigger than he had thought.
'I could never have dreamed that all the three teams [covering the entire Kowloon area] were involved,' Mr Lo said about the inquiry report.
He joined the Kowloon gully cleansing team in June last year. His job was to take workers to clear drains every night. But he said he was told to drive his vehicle around the streets to make up the mileage instead.
He has transferred to the Hong Kong team and now works the day shift from 6.30am to 3pm.
But he felt he was discriminated against.
