This just in from BBC News:
French police have made five arrests over an attack on a painting by Claude Monet in Paris, France’s AFP news agency says, quoting judicial sources….Four men and a young woman were questioned early on Tuesday and taken into custody, said AFP, citing a source close to the investigation.
I’ve tried in vain to find the story on the Agence France-Presse website, so this secondhand BBC account will have to do for now.
