BUCHAREST, Romania (AP) — Romanian prosecutors say nine health chiefs and tech giant Hewlett Packard are being probed on suspicion of wrongdoing in a health services contract that cost the state 16.8 million euros ($18.8 million).

Anti-corruption prosecutors said Monday that from 2007-2009 Romania's National House of Health Insurance signed amendments to an existing contract with HP Romania SRL, the Romanian office of the software company, for updating the institution's software.

In the amendments, Romania's national health service agreed to pay 760-800 euros ($850-$895) per person per day for HP's services. Prosecutors said HP then subcontracted the work, paying only 200 euros ($224) a day.

There was no reaction from Hewlett Packard or the Romanian health chiefs.
