Local police discovered and overturned the monolith in Schwarzenberg Park in Hamburg, Germany around 1:15pm local time on December 12, citing safety reasons.
“This is a measure to prevent danger. We noticed that the thing is shaky. And before it tips over and injures someone, we have laid it out so that no one can be injured” said police officer Michael Mannigel
After "he was killed by police officers", the monolith reappeared in the evening and eventually disappeared in the early morning.
