From what i've read in the local greek press is that migrants are also stealing and slaughtering live stock.
There have been several uprisings by failed asylum
seekers, they start fires, burnine not just tents, but also property.

Others have had their homes burglerised. There are a lot of incidents that don't make it out to the International press.

I think the writer of this article should edit and add a few examples with supporting links.
