"the British Transport Police raided a number of homes and made a bunch of arrests, seemingly as part of a pre-emptive operation to crack down on graffiti in the capital during the 2012 Olympic Games. One of the people arrested was Darren Cullen. Darren, who is also known by his graffiti tag “Ser,” has been involved in the graffiti and street art scene in the UK since 1983. But in truth, he’s kinda legit—over the past 20 years, he’s worked with local councils, companies like Microsoft, Red Bull and Adidas, disadvantaged kids, and, hilariously, Team fucking GB itself."
