Peter Chapman, the UK-based former African sales manager for Securency, late last week was convicted by a UK court on six counts of corruption relating to his dealings with an unnamed official of Nigeria's central bank.He was sentenced to time already served, some of it in an unsavoury Brazilian prison (his country of residence at the time of his arrest in 2012).Securency at the time was half owned by the Reserve Bank of Australia through Note Printing Australia.Judge Michael Grieve said a "significant factor" in mitigating Chapman's sentence was the role of Securency management, Fairfax media reports."I accept that you were put under considerable pressure by your superiors to achieve sales and you complained about that to them," the judge said."Senior management, from the managing director down, gave you the go-ahead [for the bribes]," he said. "The prosecution case throughout was that you acted with their encouragement or at least their connivance."
