The issue of Charlie Hebdo under investigation was published on 10th July last year. Its front page featured a cartoon by Laurent Sourisseau (known as Riss), accompanied by the headline "LE CORAN C'EST DE LA MERDE" ('the Koran is shit').
Charlie Hebdo has previously courted controversy by printing cartoons of Mohammed in 2006, 2011, and 2012. It also published a comic-book biography of Mohammed, titled La Vie De Mahomet (part 1, part 2).
