A 20-year-old man attacked and damaged a $26 million Pablo Picasso painting at a London museum, according to a report.

Axar.az reports citing NYpost that Shakeel Ryan Massey was charged with criminal damage for Saturday’s incident at Tate Modern. The masterpiece was identified in local media as “Bust of a Woman.”

A spokesperson for the gallery said a visitor vandalized the painting and was “swiftly apprehended.” The extent of the damage was unclear. The BBC reported the painting was ripped. The spokesperson wouldn’t comment on the work’s condition.

The 75-year-old oil painting depicts one of Picasso’s lovers, the photographer Dora Maar, in a semi-abstract style, wearing a hat and green clothing while sitting on a black metal chair.
