A 20-year-old is facing charges after he allegedly attacked a Picasso painting hanging on the wall of London's Tate Modern. Picasso's Bust of a Woman, valued at $26.5 million, is being assessed for damage after it was reportedly ripped on Saturday, per the BBC. A museum spokesperson gave no details on the condition of the 1944 painting of Picasso's lover Dora Maar—depicting the French photographer in green garb and a hat, per the New York Post—saying only that it was "with our conservation team for expert assessment" while the museum remains open. Shakeel Massey of North London indicated he'd deny a charge of criminal damage at a Monday court hearing where bail was denied, per the BBC. A pretrial hearing is set for Jan. 30.
