More than a dozen vandals damaged Facebook’s German headquarters in Hamburg, smashing glass and spray-painting “Facebook dislike” on a wall, police said Sunday.
Up to 20 people wearing black clothes and hoods were behind the overnight defacement, which authorities are investigating, Reuters reports. They also threw paint bombs and damaged doors and windows, authorities said.
There were no injuries, a spokesperson for the social network told the news agency.
The motive behind the group’s attack is unclear. It comes as Martin Ott, the European head of Facebook, is being probed in Germany over the Facebook’s alleged failure to remove racist hate speech amid anti-refugee comments, according to Reuters.
