Vandal Sprays Poussin

Yesterday afternoon, a nutter in The National Gallery, London, sprayed red paint on two paintings by Nicholas Poussin: The Adoration of the Golden Calf (above) and The Adoration of the Shepherds, both hung in Room 19. A gallery assistant swiftly raised the alarm; police were called and a man arrested. Neither of the paintings - both dating from 1633/34 - was permanently damaged. They were cleaned and re-hung in their usual place (title link). The Guardian has already posted a photo of the actual red paint (CLICK). I wonder whom it bribed to get that.
