Forestry officials have been tracking the boar in question for some time, Ms Kammer said.
"Fortunately, there have not been any serious incidents involving wild boar at the Teufelssee."
Wild boar numbers are regularly controlled by licensed hunters around Berlin and many other major German cities.
When the population becomes too high. the boars emerge from the forests to look for food and can turn aggressive when they encounters humans.
In one famous incident, four people including a police officer were injured when they were attacked by a 265-pound boar that had wandered into the Berlin neighbourhood of Charlottenburg in 2012.
The clothes-thief boar involved may have been enticed to the popular bathing spot by the large volume of rubbish left behind by visitors, Ms Kammer said.
A licensed hunter will be commissioned to track and shoot the boar. However there is still hope of a reprieve.
Forestry officials said it was too dangerous to hunt the boar while the forest is still crowded with people seeking to escape the city heat, and any action would probably be delayed until the winter.
In addition, the female boar in question still has young, and it is illegal to kill mother boars if they have cubs younger than six months.
