Walking around Geneva - Something is happening on the Bridge

I've decided to start a new series about the things I see while wandering around Geneva. I've had more time recently to enjoy life, and I've been walking a lot, as means of staying in shape. My old days of running like a maniac are temporarily suspended. Anywho, we'll see if I can keep this going...

So here is something I saw one sunny day while crossing the river on the pedestrian bridge. I don't know if someone jumped, dropped something important - like an expensive watch or a dog - in the water... I just know there was a serious looking crew of Police with dudes on speed boats and divers in gear. Pretty cool... Judging by the interest amongst the public it must have been something interesting...
