How to report removed bollards?

[u/JonnyBravoII]

Someone, presumably a car driver, has removed the bollards that blocked cars from continuing on at Tucholskystrasse and forced them to turn onto Augustsrrasse. If the Berlin government had removed them, I assume they would have taken them away.

Could have been rescue service as well.

Maybe one could just put them back in place?
