Just got back from Paris and just thought I would let potential visitors about current scams
One is that men will approach you and ask where you are from etc being really friendly and attempt to give you a necklace or bracelet, but once these are attached to you it is a sign for people else where to target you.
They do this to the people who look like they will be carrying a lot of money so for example people who walk around with huge cameras or really big rings/watches and once you have this bracelet/necklace it's a sign for others to try steal from you.
Another is when you are walking on a bridge a man/woman will be walking and will bend down to pick something up. This is a gold ring which is heavy and stamped as though it is an 18ct gold ring and they pretend to be confused and offer you the ring as if you had just dropped it. Then they follow you continuously if you accept the ring and demand payment for them finding it.
There are obviously loads more and pick pockets etc so just be careful.
