Edmond Sikua's arrest came after police accused him of awarding Government tenders worth over 630,000 Solomon Islands dollars ($630,436.50) or $US80,000, to Beeds Investment, a company registered and owned by his two daughters.
Mr Sikua appeared in the Honiara Magistrate's Court this week on seven counts of official corruption and was released on a bail of 2,000 Solomon Islands dollars or $US 256, with strict conditions.
Solomon Star reports Mr Sikua was first appointed permanent secretary in 2012.
