A mass brawl and property damage incident occurred at a boat party at Hennesee in the Sauerland region during the night of October 3. The disturbance reportedly began after security personnel expelled an individual for aggressive behavior. In response, some partygoers showed solidarity, leading to physical altercations involving between 30 and 50 people.

During the chaos, individuals on the shore allegedly threw stones at a moored passenger ship, breaking at least five windows. While initial reports indicated at least five people sustained minor injuries, police in the Hochsauerlandkreis district noted that the total number of casualties remains unclear, as some individuals left the scene before being identified. 

Authorities are currently investigating the incident, seeking witnesses and victims to clarify the roles of those involved in the assault, property damage, and breach of the peace.
