The case of Irianna V.L. refers to the arrest, trial, conviction and reactions of PhD student Irianna Vl. for participating in the terrorist organization "Conspiracy of Fire Nuclei". Irianna V.L. was found innocent after she appealed.

The case began in March 2011 with the issuance of a warrant for the arrest of three members of the Core of Fire while a search was carried out at the home where Irianna's partner resided. Irianna gave a testimony to Greek police and voluntarily a DNA sample. In November 2011, arms were found in Polytechnic School of Athens, by accident. Police found a small sample of DNA, that matched Irianna's DNA. The identification was disputed because the material was below the threshold for safe conclusions, there was no sample for re-inspection and for other technical reasons. Another issue that caused controversy is that the court took into consideration social contacts and relations of Irianna, most notably a trip to Barcelona, a city that hosts many anarchists. Irinna's sentence of 13 years was met with skepticism as the principle of Presumption of innocence was shaken.

In 2018, Irianna was freed after a second degree trial.^[1]
