Four individuals have being investigated in France over an August 2015 plot to attack Americans on a high-speed train.
Ayoub El-Khazzani is blamed for starting to shoot at board a train venturing out from Amsterdam to Paris; three months before the Paris attack.
Two person were injured before he was overwhelmed by travelers.
Nobody passed on in the incident, which propelled a Clint Eastwood spine chiller The 15:17 to Paris.
Three others are associated with helping Mr El-Khazzani plan the assault. Bilal Chatra, Mohamed Bakkali; and Redouane Sebbar deal with lesser indictments than the supposed shooter. This includes conspiring with terrorists and complicity in attempted murder.
