Boy punches hole in 17th century Italian masterpiece - VIDEO
The video, released by the organisers, shows the youth sauntering past the painting while holding a drink. As he approaches the work, he stumbles and stretches out his hand to break his fall, with his left fist going through the canvass.
He looks up, freezes, then turns around looking at the other people in the room.
Organisers of the exhibition say the boy will not be blamed and the family not asked to pay for the restoration.
The painting is to be repaired by a Taiwanese art restorer before being shipped back to Italy.
