A TOP prosecutor found dead in the bathroom of his apartment had drafted an arrest warrant for the President of Argentina, Cristina Fernández de Kirchner, sparking further mystery in a case that has gripped the country.

Alberto Nisman, 51, was found dead in his apartment on January 18 with a single gunshot wound to the head and no suicide note. It was hours before he was due to testify to Congress about the President’s role in allegedly covering up details of a 1994 bombing at a Jewish centre which killed 85 people and injured 200.

Lead investigator in the case of Mr Nisman’s death Viviana Fein confirmed the 26-page draft document calling for the arrest of President Kirchner and foreign minister Hector Timerman was found in the rubbish at Mr Nisman’s apartment.

Political analyst Sergio Berensztein told The New York Times the warrant would have “provoked a crisis without precedents” in the country.

“It would have been a scandal on a level previously unseen,” he said.

It’s the latest development in a scandal that has seen the secret service disbanded and prompted a myriad of conspiracy theories, with thousands turning out to protest “crisis Argentina”.

Before his death, Mr Nisman was responsible for investigating who was behind the 1994 bombings at the Jewish centre. He had filed a 289-page criminal complaint against the President and key supporters including the foreign minister, accusing them of protecting former Iranian officials allegedly behind the 1994 bombing of the Argentine-Jewish Mutual Association.

Mrs Kirchner and Mr Timerman have denied any involvement and the bombing remains unsolved.

The death of Mr Nisman has sparked outrage in the country with his supporters saying there is no way it could have been suicide, prompting speculation of a high-level cover up.

Mr Nisman had 10 federal police assigned to protect him at the time of his death but all have been suspended while investigations are underway.

Investigators are initially treating it as a suicide, but homicide or ‘induced suicide’ have not been ruled out.

Ms Fein said this week the only DNA found on the gun and ammunition belonged to Mr Nisman. She also said a security camera in the service lift of the apartment was not working and no cameras were in the stairwell.

President Kirchner has suggested the death was the result of rogue elements in the intelligence community, implying Mr Nisman was being fed false information by an official who oversaw a wire-tapping operation.

She has also urged the investigation of Mr Nisman’s long-time friend Diego Lagomarsino, who gave him the gun one day before he was shot at Mr Nisman’s request to protect his daughters.

There are no suspects in the case at this stage.

In the wake of the death, President Kirchner ordered the secret service disbanded and the creation of a new intelligence agency with less influence on political cases.

It’s also created outrage in Argentina’s Jewish community, which is one of the largest outside of Israel. Mr Nisman’s Jewish background prompted religious groups to boycott Holocaust commemorations last week over his death and call for truth from officials.

The Delegation of Jewish-Argentine Associations treasurer, Mario Comisarenco said: “In honour of the victims, we are not going to share a table with those who don’t give us the truth, much less justice.”

Investigations are continuing into the death.
