Mark Kennedy (Mark Stone, Flash)

2003–2010

Mark Kennedy infiltrated many environmentalist, anti-capitalist, and anarchist groups in the United Kingdom and abroad. He participated in demonstrations, actions, and other events in Denmark, France, Germany, Greece, Iceland, Italy, Ireland, Poland, Spain, and the United States. He worked for the police as part of the National Public Order Intelligence Unit. In 2010, he also worked for a security company. He first infiltrated a social center in Nottingham, United Kingdom, before moving on to other groups. He had credit cards, bank accounts, a passport, and a driver's license under his fake name. On one occasion, he introduced two people he claimed were his childhood friends to his roommates, and who were in fact likely other undercover police officers. On one occasion, he used a modified watch to record his targets' conversations. He had many romantic and sexual relationships with his targets, including one that lasted six years.

His targets were unaware that he was married and had children under his real identity. He was identified because:

- One day, his long-term partner found his real passport under the name “Mark Kennedy,” as well as emails indicating that he had children.
- His long-term partner and other activists then found evidence of his real identity:
  - Electoral records for his birth year did not include an entry for “Mark Stone” but did include an entry for a “Mark Kennedy” who was married.
  - A genealogy website included an entry for a “Mark John Kennedy” who was listed as being married and having children.
  - The birth certificate of the son of “Mark Kennedy” listed the father's occupation as police officer.
  - The birth certificate of “Mark Kennedy” listed the father's occupation as police officer, despite his claims that his father was an accountant.
  - The marriage certificate of “Mark Kennedy” listed his occupation as police officer.
- When confronted with evidence, he admitted to being an infiltrator.

Edward Nicholas Gratwick (Radio Nick)

1995–2006

Edward Nicholas Gratwick infiltrated environmentalist and animal rights groups in the United Kingdom. He also attended a protest in the Czech Republic. He worked for the security company Verify. From 1995 to 2003, he worked on behalf of the police, and then he worked on behalf of private companies. He participated in and helped organize many demonstrations, events, and actions. On many occasions, the police seemingly disrupted or prevented actions based on information he provided. On one occasion, he accused another activist of being an infiltrator. He had a sexual relationship with one of his targets.

He was identified because:

- He exhibited suspicious behavior. For example, in 2003, he requested to be named as a defendant in a civil court case against activists, presumably to gain access to their legal strategy. This was considered suspicious because activists would not normally want to be named as defendants as this would expose them to fines or other negative consequences.
- In 2004 or 2005, an activist revealed that a “well-placed contact within the security industry” had claimed that Gratwick was an infiltrator working for the security company Verify.
- In 2015, an activist learned that, in 2002, former infiltrator Jim Boyling had claimed that Gratwick was an infiltrator.
- In 2016, a company was founded at the address where the security company Verify had been based. The company listed two directors: Gratwick and the son of the founders of Verify.
- In 2025, he was accused of child sexual offenses. During the trial, as part of his legal defense strategy, he admitted that he had been an infiltrator.
