At Frankfurt Airport, Ageeb physically resisted the three Bundesgrenzschutz officers who escorted him onto Lufthansa Flight 588 travelling to Sudan on 28 May 1999.
[1][2] They restrained him with several ropes, handcuffs and bands; put a helmet on his head; leaned on his chest; and pushed his head between his knees, apparently all in accordance with procedures in use at the time.
[2] The three officers were charged with voluntary manslaughter (German: Körperverletzung mit Todesfolge, literally 'bodily harm with fatality') and found responsible for the death.
Instead of the minimum sentence of one year, Judge Heinrik Gehrke imposed nine months probation, in order to avoid the officers losing their right to work in civil service.
[3] The incident contributed to protests against Lufthansa's role in air deportations.
