The entrance to the Karlplatz underground station
Musician Michael Buchmann, 48, who plays with the acclaimed Vienna Symphony Orchestra, was attacked on the city’s underground, known as the U-bahn, and left with a broken finger.
Mr Buchmann had returned from a concert by the orchestra in the German city of Dortmund and was waiting for a train on the U4 station Karsplatz.
It is alleged that Mr Buchmann then got into an argument with three youths because one of them was supposedly smoking on the platform, which is banned on the Vienna network.
He said: “While I was waiting for a U4 train at Karlsplatz I noticed a smell of cigarette smoke.
“A group of three young men were standing next to me and one of them was smoking.”

He also claims he was grabbed by the throat by one of the men.
The assault broke the third finger on his left hand. The three men then fled the scene before the police could arrive.

He said: “As a strings player, I rely professionally on my fingers. If the movement of my finger is in any way restricted, it would be devastating.”
Police said that they were still investigating the incident and confirmed that witnesses had come forward to verify the claims by the violist.
