William Pina Botelho infiltrated groups in Brazil, including an informal group that was planning an anti-government demonstration. He worked for the military. He attended and helped organize demonstrations.

He was identified because:

  • He and other activists were arrested while gathering before a demonstration, and:
    • He was the only one of those arrested who was not taken to a police station.
    • While the activists were in custody, he posted messages on social media, further confirming that he wasn't in custody.
  • Social media pictures of him under his cover identity matched social media pictures of him under his real identity.
