(ANSA) - Florence, January 9 - A 51-yewar-old Czech man who attacked Serbian performance artist Martina Abramovic in September 2018 was found nude in the courtyard of the Tuscan capital's Palazzo Strozzi on Wednesday.

The man was stopped while taking off his clothes to climb the stairs to the artists's current show at the storied Renaissance palazzo.

He was wearing a mask with the face of controversial artist Maurizio Cattelan and had a picture frame around his neck.

The man risks a fine of between 5,000 and 30,000 euros for public indecency.

On September 23 2018 the self-styled artist broke a painting over Abramovic's head in the same courtyard, without injuring her.
