This from The Londonist, under the following headline:
Graffiti: Tox Could Go To Jail
One of London’s most prolific taggers has been convicted of criminal damage. Daniel Halpin of Camden, better known as Tox, has at least a decade of defacement to his name. His tag, which simply states ‘Tox’ followed by the last two digits of the year, can be seen all over the country and particularly on London’s rail networks.
Eye's heart bleeds for him. No, stop laughing! Honestly, it really does. Okay it doesn't.
