The suspect reportedly met with the attacker prior to the incident, which resulted in life-threatening injuries to a Spanish tourist. He faces charges of aiding and abetting attempted murder and aggravated bodily harm. The attacker, who was 19 years old at the time and had recently arrived in Germany as an unaccompanied minor, was sentenced to 13 years in prison in March 2026 for the attack, which was motivated by Islamist extremism. The case remains under judicial review.
