Cartrain (born 1991?), often stylised cartяain, is a British artist associated with the graffiti urban art movement. YBA artist Damien Hirst has threatened to take legal steps against Cartain over his art and activities. Cartrain's art has also been appropriated by well-known artists such as Gilbert and George, Jamie Reid, David Shrigley  and Mr Brainwash 
Cartrain said the choice of pseudonym was "random". From Leytonstone, East London, he started doing graffiti art at the age of 12, and initially worked in his local area, but "because no one pays any attention" had moved on by the age of 15 to the back streets near Old Street and Brick Lane in Hackney, and also to central London, even spraying on walls opposite the Houses of Parliament.
His work is left-wing in content and often features notable mainstream figures such as George Bush and the Queen.
Cartrain started photographing abandoned buildings in 2007 and has been a major influence in the sport of Urban Exploration. He has explored over 150 buildings without permission since 2009 including Millennium Mills, Lots Road Power Station, St Mary's tube station and Walthamstow Stadium.
Interaction with Hirst
In December 2008, Damien Hirst contacted the Design and Artists Copyright Society (DACS) demanding action be taken over works containing images of his skull sculpture For the Love of God made by then-16 year old Cartrain, and sold on the internet gallery 100artworks.com. On the advice of his gallery, Cartrain handed over the artworks to DACS and forfeited the £200 he had made; he said, "I met Christian Zimmermann [from DACS] who told me Hirst personally ordered action on the matter."
A spokeswoman for Hirst said: "Damien is not suing Cartrain. This is a straightforward issue of copyright. Damien owns the copyright to the diamond skull and its image and if it is reproduced without his permission DACS are instructed to deal with this on his behalf."
Copyright lawyer Paul Tackaberry compared the two images and said, "This is fairly non-contentious legally. Ask yourself, what portion of the original--and not just the quantity but also the quality--appears in the new work? If a 'substantial portion' of the 'original' appears in the new work, then that's all you need for copyright infringement... Quantitatively about 80% of the skull is in the second image."
In July 2009, Cartrain walked into Tate Britain and removed a packet of Faber Castell 1990 Mongol 482 series pencils from Damien Hirst's installation, Pharmacy. Cartrain then made a fake police "Wanted" poster, which was distributed around London, stating that the pencils had been stolen and that if anyone had any information they should call the police on the phone number advertised. Cartrain made this statement:
- For the safe return of Damien Hirsts pencils I would like my artworks back that Dacs and Hirst took off me in November. Its not a large demand he can have his pencils back when I get my artwork back. Dacs are now not taking any notice of my emails and I have asked nicely more than five times to try and resolve this matter. Hirst has until the end of this month to resolve this or on 31 July the pencils will be sharpened. He has been warned.
In December 2009 The Metropolitan police dropped all charges against Cartrain. The Independent wrote: "Cartrain told me that, happily, all police charges have since been dropped and that he's even had a meeting with the Tate to discuss the issue.What's more, he came face to face with Hirst himself at the latter's current show at London's White Cube gallery."
On 10 November 2010, Cartrain and fellow street artist Vagabond managed to smuggle a Cannabis joint inside the Palace of Westminster. Whilst Nick Clegg was answering PM's questions he proceeded to light up and shout "Decriminalise Cannabis" in the House Of Commons and then passed the joint around each other. They were later cautioned and released without charge.
Cartrain in a statement told the Evening Standard: "They said they would put me in a cell under Big Ben, which I said sounds amazing, like the most expensive hotel in London, but then they decided to let me go when they realised I was quite keen to be arrested."
Cartrain has posted a video on YouTube, showing himself putting up a piece of cardboard box as a conceptual artwork in Tate Modern; he states, "i mannaged [sic] to put my cardboard box up in the tate modern for two hours without being spotted as a fake." Another video shows him installing a collage incorporating Hirst's skull image, and titled "Damien Hirst", in the National Portrait Gallery.
