, spray-painting "Facebook dislike" on a wall, and causing some minor property damage. From the story: "A Facebook spokesman said nobody was injured in the incident. He said he could not immediately comment on the possible motive for the act of vandalism.

The investigation was announced last month as German politicians and celebrities voiced concern about the rise of anti-foreigner comments in German on Facebook and other social media as the country struggles to cope with a refugee influx.
