Alberto Nisman (pictured) was discovered dead in his own apartment in January - a day before he was due to testify about his claims . An Argentine prosecutor's mysterious death days after he made criminal charges against President Cristina Fernandez is part of an attempt to unseat her and bring neoliberals back to power, a senior government official has claimed. Gustavo Lopez, an undersecretary in the presidency, said Alberto Nisman's death last month was part of a coup. He wrote in a statement: 'We are facing an attempted coup d'etat, that aims to get rid of the president, to end this political project that has been governing since 2003 and to restore the neoliberal conservative forces that governed for decades to reap their own benefits.' Lopez said the government of Fernandez and her late husband and predecessor Nestor Kirchner had confronted many sinister forces during their years in power such as the 'international economic interests that live from usury, weapons trafficking and money laundering.' He said: 'Now they have come to get their revenge. They cannot stand the Front for Victory (ruling coalition) winning another presidential period and if they need to provoke a political death to achieve this, they will do it.' Nisman had accused President Cristina Fernandez of covering up Iran's alleged role in the 1994 bombing of a Jewish centre in Buenos Aires that left 85 dead. His body was discovered in an apartment - a day before he was due to testify about his claim that Fernandez sought to whitewash his findings that Iran was behind the attack on the centre, run by the Argentine Israelite Mutual Association. This week, Argentine investigators revealed they had found a second person's DNA in the apartment where Nisman was found dead. Following the find, Judge Fabiana Palmaghini is calling in a person who visited Nisman the day before his body was found. The judge's office does not name the witness, but Nisman's aide Diego Lagomarsino has acknowledged visiting him on January 17. Investigators say they don't yet know if Nisman committed suicide or was killed. Last week, it was reported that investigators are trying to track down former intelligence chief Antonio Stiusso in connection with Nisman's death, but are unsure if he is even in the country. 'He was not at any of the properties registered as his own,' Oscar Parrilli, head of the Intelligence Secretariat (SI), told . reporters. Iran has vigorously denied involvement in the bombing and .
