About
Zeus SL is a company whose relevance stems from its connection to an ongoing investigation into alleged embezzlement at the Centro Nacional de Investigaciones Oncológicas (CNIO), Spain's National Cancer Research Center. The investigation centers around Juan Arroyo, the former manager of CNIO, who is accused of misappropriating between €25 and €30 million over 17 years. Recent news reports highlight a potential conflict of interest involving Mariano Barbacid, a prominent scientist at CNIO, who reportedly provided Arroyo with a protective contract. Furthermore, Zeus SL shares a registered address with private businesses belonging to both Barbacid and Arroyo, as well as with a company implicated in the alleged embezzlement. This shared address raises questions about potential connections and the extent of involvement in the alleged financial irregularities. The investigation is being conducted by the Anti-Corruption Prosecutor's Office and the National Police, and has led to the dismissal of Arroyo and two subordinates.
