المهدي بن بركة
Georges-Auguste Figon (21 October 1926 – 17 January 1966) was a French chemist who was a freelance "barbouze" (secret agent). He arranged the meeting with Mehdi Ben Barka in the "Brasserie Lipp" in Paris. He later told "L'Express" that he knew who killed Barka and accused General Oufkir, whom Figon had seen torturing Barka.
