Federal Judge Julián Ercolini ordered the prosecution of Diego Lagomarsino on Tuesday for considering him "a necessary participant" in the murder of prosecutor Alberto Nisman.

"I resolve to order the prosecution of Diego Ángel Lagomarsino, as he is criminally responsible for the crime of simple homicide aggravated by the use of firearms, as a necessary participant," the magistrate said in his ruling.

In addition, Ercolini froze the accounts and locked a $ 15 million seizure on the computer technician, who will not be imprisoned but will remain under surveillance by an electronic anklet.

In a resolution of 656 pages, the judge also prosecuted the four custodians who were in charge of Nisman's security, for "aggravated concealment" and "failure to comply with the duties of a public official."
