The Gladbeck hostage crisis was a bank robbery and hostage-taking that unfolded across West Germany over 54 hours, from 16 to 18 August 1988. On the morning of 16 August, Hans-Jürgen Rösner and Dieter Degowski, both of whom had extensive prior criminal records, broke into a Deutsche Bank branch in the Rentfort-Nord district of Gladbeck, North Rhine-Westphalia, before it opened for business. After spotting a police car outside, the two men took two bank employees hostage. Following negotiations conducted through bank director Wolfgang Schöning, police handed over 300,000 DM and a getaway car that had been secretly fitted with tracking and listening devices. Rösner's girlfriend, Marion Löblich, joined the pair as they drove north, and the group abandoned several vehicles they suspected were police decoys.
In the early hours of 17 August, the trio reached Bremen. That evening, Rösner and Degowski hijacked public bus Line 53 with 32 passengers aboard, including five children. What followed became a defining episode in West German media history: reporters and camera crews were allowed onto the bus and interviewed both hostages and hostage-takers, at times supplying them with coffee and directions, while police held back and did not attempt a rescue. A press photographer relayed the abductors' demands to police in place of a trained negotiator, and Rösner at one point held a gun to the head of a 9-year-old hostage, Tatiana De Giorgi, in view of television cameras. At a highway rest stop near Sottrum that night, after a police deadline passed, Degowski shot 14-year-old hostage Emanuele De Giorgi in the head; the boy died in hospital two hours later. A 31-year-old police officer, Ingo Hagen, was separately killed in a traffic collision while pursuing the group.
On 18 August, the bus crossed into the Netherlands, where Dutch police refused to negotiate while children remained aboard; the women and children hostages were released shortly afterward. Rösner and Degowski then continued toward Cologne in a police-prepared BMW, keeping two 18-year-old hostages, Silke Bischoff and Ines Voitle. In central Cologne, surrounded by press and bystanders, journalist Udo Röbel got into the car and guided the two men onto the A3 motorway before being dropped off. Near Bad Honnef, police officer Willi Rupieper rammed the getaway car, and officers exchanged gunfire with Rösner during the resulting standoff. Voitle was wounded by a police ricochet but escaped; Bischoff was fatally shot by Rösner. Rösner and Löblich then surrendered.
In March 1991, a regional court in Essen convicted Rösner and Degowski of murder and sentenced both to life in prison; Löblich received a nine-year sentence for her role as an accomplice. Degowski's sentence was later increased on appeal, and he was released on parole in August 2018 after serving 30 years. The extensive, unimpeded access given to journalists throughout the crisis — including live interviews with the hostage-takers — drew sustained criticism and led the German Press Council to ban future interviews with hostage-takers during active hostage situations.
