This is the moment a brazen thief steals a famous painting in front of staff and tourists at Russia's top art gallery in broad daylight yesterday.

Police have arrested a man they believe stole the artwork, 'Ai-Petri. Crimea', painted by 19th century artist Arkhip Kuindzhi.

State television aired footage of a man calmly taking the painting off the wall at Moscow's Tretyakov Gallery and walking away with it.
