The third of three Swiss youths accused of attacking five people in Munich has admitted his involvement in the 2009 incident.
The young man, who is now 18 years old, made his confession on Thursday – shortly before the court case was due to wrap up.
He and his two co-accused are charged with attempted murder and serious bodily injury.
According to his lawyer, the young man has written a letter of apology to the primary victim.
The three teenagers from the Zurich area randomly attacked five strangers in Munich while on a school trip on June 30, 2009. Apparently, the boys had been drinking.
The victims of their 30-minute rampage included a 46-year-old man whom they nearly beat to death. They also attacked a disabled man and a Bulgarian student.
The defendants, who have previous convictions in Switzerland, face up to ten years in prison.
