The Swiss man, who is 30-years-old, faces up to five years in prison if convicted.
Police arrested him in early March in a flat in Vienna’s Rudolfsheim-Fünfhaus district. An anonymous tip-off led police to the commune where he was living. Three other graffiti sprayers were also arrested.
Since then Puber has been in custody, despite the efforts of a Facebook group who campaigned for his release.
Vienna city council and Wiener Linien (Vienna public transport) have been asked to give witness statements, along with 30 private individuals and companies.
Puber, who left his mark mostly around the 7th district, was extremely unpopular in Vienna - even with other graffiti artists as he would spray over their work.
