While the perpetrators of the bombing were never found, four individuals were subsequently arrested as a result of the investigation. Stéphane Phillipe, Pascal Laizé, and Christian Gorgeault (the presumed ARB ringleader) were arrested for suspected complicity; Gael Roblin, the main spokesman of Emgann, was also arrested for his theoretical justification of previous ARB bombings. The four men were ultimately acquitted of charges in the Quévert bombing, but they were sentenced the same day to serve prison terms (six, eight, eleven, and three years respectively) for their involvement in prior attacks.
