2015–2021

Sergio Gigirey Amado infiltrated groups in Madrid, including the antifascist group Distrito 14, and the Movimiento Antirrepresivo de Madrid (Madrid Anti-Repression Movement). He first infiltrated a food bank before moving on to other groups. He attended meetings and participated in civil disobedience actions. On some occasions, he and another infiltrator, Carlos Pérez Moreno, participated in the same actions. He shared an apartment with some of his targets and was in a romantic and sexual relationship with one of his targets for several years.

- Pictures of him under his assumed identity matched pictures of him under his real identity. The latter included a video from his police graduation ceremony and a picture from a race for which he registered under his real name.
- An employer for whom he claimed to work denied employing him.
