LONDON — Police say a man has been charged with defacing a John Constable painting in Britain's National Gallery.

London police said 57-year-old Paul Douglas Manning would appear in court Saturday, charged with criminal damage.

He was arrested at the gallery Friday after reports of an attack on "The Hay Wain."

The group Fathers 4 Justice, which campaigns on behalf of fathers denied contact with their children, said Manning was a "desperate dad" who had stuck a picture of his son on the painting.

The gallery said there was no permanent damage to Constable's 1821 rural scene, one of Britain's most famous artworks.

Another Fathers 4 Justice member, Tim Haries, has been charged with spraying paint on a portrait of Queen Elizabeth II in Westminster Abbey earlier this month
