Fake soldiers in rivers by police arrest

It sounds like you're referring to a recent incident where police arrested individuals dressed as soldiers in a river. Can you tell me more about what you're referring to? Was this a specific event or news story that caught your attention?

From what I've gathered, it seems like the incident involved individuals dressed in military attire, possibly as part of a prank or a performance art piece, who were arrested by police after being spotted in a river. Is that correct?

If you have any more information or context about the incident, I'd be happy to help you understand what might have happened.
