Celle Hole (German: Celler Loch) 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' (German: Aktion Feuerzauber).
The secret services used a stolen Mercedes SL, 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 passport with a photograph of Sigurd Debus. Serial numbers of the passports showed that they were stolen from German authorities. Mr. Debus was an inmate in the Celle prison. He was considered as a Red Army Faction terrorist suspect. Some tools to be used for a prison escape attempt were brought secretly to Mr. Debus' prison cell by the secret services.
The action should have had taken place one night earlier when twelve secret service officers, one GSG 9 demolition squad officer and Jürgen Wiehe, a civil servant in the ministry of interior of the state of Lower Saxony (Niedersachsen) waited for the right moment to detonate the bomb on July 24. But they had to interrupt the action since two lovers coming from the nearby funfair entered the danger area. So the action was deferred.
On July 25, 1978 at 2.54 a.m. the bomb was detonated at the outer prison wall, but caused minor damage only. No inmate was able to escape. The Mercedes was caught later in Salzgitter (80 km away) in a police road block, the driver escaped. The false passports and some ammunition was 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. Celle prison is situated close to the bank of river Aller. After the detonation, Mr. Debus' conditions of detention were aggravated "for security reasons". The secret service had planted escape tools into Debus' cell, which were found in the search after the attack, and was supposed to prove Debus' participation. Hence, the detainee started a hunger strike as a protest against this. Sigurd Debus died on April 16, 1981 shortly before the date of his discharge from prison.
