A single object, a single shape, a single colour,' is how Anish Kapoor summed up Leviathan, his response to the Monumenta challenge this year. Radically departing from Christian Boltanski’s busy collage-like approach in Personnes for Monumenta 2010, Kapoor has filled the 13,500 square metre space with a single cavernous entity which surges through the Grand Palais roof.

The first images of the 1001bhp monster were released via facebook on Thursday. Now the force has also published a video of the car, which joins the likes of McLaren, Lamborghini and Ferrari in Dubai Police’s fleet of supercars. The police have said that it is using supercars to show the world how progressive Dubai is and to demonstrate why it is the right city to host major events such as Expo 2020.

These powerful images capture the spear-wielding tribes of Papua new Guinea who believe they are possessed with the spirit of the crocodile. They show how the Kangunaman clansmen scar their backs to resemble reptile scales while the Huli Wigmen wear elaborate headdresses to signal they are ready for battle.
