The Frederiksburg District Court found him guilty on racism in January 2011, but did not sentence him because the judge said he did not know that his comments made in a private setting would be published in another person's blog.
In May the same year he was fined 5000 krona by Eastern High Court that overturned the earlier decision, for racist comments.
This is the info on him as far as I know it.
The only detail I have momentarily mistaken is that this Lars Hedegaard and the cartoonist by the Jllstad Posten - who also got attacked in past years - have been taken for one and the same person by me, but in fact are two. Mistaking people for somebody else can happen if you are not familiar with the sound of names in another language you are not so familiar with. And Danish I do not understand, except "tak".
