This man is Jean-Claude Mas.br He founded french firm, Poly Implant Prothese (PIP) which is at the centre of a global breast implants scare.br Mas is wanted by Costa Rica for "life and health" offences, according to a notice posted on the website of the international police agency Interpol.br He was arrested in Costa Rica in 2010 for reckless driving but fled the country before the court date.br It is unclear if there is any link between that arrest and the Interpol notice.br PIP produced about 100,000 implants a year for the better part of two decades before its products were ordered off the market last year.br Many of the implants were made of cheap industrial silicone and some surgeons had reported abnormally high rupture rates.br There was no evidence of an increased cancer risk.br One surgeon who knew Mas said he did not come from a medical background.br (SOUNDBITE) (French) PLASTIC SURGEON PATRICK BARAF, SAYING:br "We are not in an experimental field, but it's possible to be tricked. And in the case of PIP, it was run by a man with a commercial background not a medical one. This man is a salesman, a tradesman. I have nothing against tradesmen, I have nothing against butchers, which is what he was, and I have nothing against wine sellers, because he had done that, but I ask you, are these people qualified to manufacture medical materials, with medical concepts? Do we trust these people? Do we trust salesmen when they talk?"br France has advised thousands of women to seek removal of the implants.br The lawyer for French PIP implant users, said a fault in the reporting system could be seen.br (SOUNDBITE) (French) LAWYER PHILIPPE COURTOIS SAYING:br "What is certain is that there are grave concerns in this dossier. In nine months the health and safety watchdog AFSAPS received three times the number of complaints of problems or ruptures with PIP implants than in the nine previous years. So either the surgeons didn't pass on the information to AFSAPS themselves, or AFSAPS didn't properly treat the information it was given."br As many as 300,000 women could be affected worldwide.br PIP's company lawyer said it recognises its products were defective but argues it is being unduly singled out.br He said Mas is in France but does not intend to make a public comment.
