Does the police station have the right to jointly cut off the charging line pulled by the community owner?

The property has the right to do so. The owner pulls the charging cable from home to the public area for charging, which will cause hidden dangers to safety. Eliminating potential safety hazards is the obligation of the property. But remind the property before cutting.

The police station has no right to do this, because it is not within the scope of the police station. What you should say is to call the police after you find the property, and then cut it in front of the police.
