The French-speaking news outletRTL reported that the attacker had started screaming in the station before stabbing the victim who was left with blood "on his face and on his hands." A Frenchman, who works as a police officer in his native country, subsequently intervened and tackled the man to the ground.
The assailant was subsequently handcuffed by the security guards and was later arrested by police reinforcements, while the victim is currently being treated at a hospital.
