Pablo Picasso was questioned as a suspect in the 1911 theft of the Mona Lisa

Explanation

When the Mona Lisa was stolen in 1911, police discovered that Picasso had kept two Iberian statues stolen from the Louvre in his apartment (unrelated to the heist) and his friend, the poet Guillaume Apollinaire, was even briefly jailed over the affair. Picasso was questioned and released, and the painting was recovered in 1913, having been stolen by Vincenzo Peruggia, who wanted to return it to Italy.
