Madrid municipality has spent 200,000 euros in the last seven months to clean up the graffiti. A few weeks ago, the Municipal Police captured Roco.

Days later, Kdys - who also signs as Kdis or Kdes - was killed, a minor to whom hundreds of graffiti were attributed. The City Council has administratively and criminally prosecuted both, while the persecution continues against another handful of graffiti artists who, they claim, have already been identified. The greatest difficulty of the investigation is discovering the graffiti artists in flagrante delicto.
