Celle Hole () was a breach in the outer wall of the prison of Celle, Germany. First used on July 25, 1978, the name was part of a campaign by one of the West German secret services (Landesbehörde für Verfassungsschutz) and the GSG 9 in an attempt to lay blame on the Red Army Faction, West Germany's most active and prominent left-wing terrorist group. However, the incident was revealed in 1986 to be a plot by the government, a false flag operation, much to the embarrassment of the government. The Verfassungsschutz used the name 'Operation Fire Magic' (). The secret services used a stolen Mercedes-Benz SL (R107), driven by two criminals named Klaus-Dieter Loudil and Manfred Berger who were recruited by the secret services. In the car were forged passports, one of them with a photograph of Sigurd Debus. Serial numbers of the passports showed that they were stolen from German authorities.

On July 25, 1978, at 2.54 a.m., the bomb was detonated at the outer prison wall, but caused minor damage. No inmate was able to escape. The Mercedes was later caught in Salzgitter (80 km away) in a police roadblock, with the driver having already escaped. The false passports and some ammunition were found in the car. In Celle, a 1.5 square meter hole, named the Celle Hole (Celler Loch), was left in the outer prison wall. A handgun, model Walther PPK 7.65, which was the official pistol of one of the secret service officers, as well as a rubber dinghy, were found. The Celle prison is situated close to the bank of the river Aller. After the detonation, Debus' conditions of detention were aggravated "for security reasons". The secret service had planted
