They picked my pocket in an organized way :-(

Today when I was coming back from work, I encountered a group of culprits.

They were more than three or five - I have no clear idea of it, and they were pretty much organized. One of them engaged me in conversation to divert my attention and someone from their group picked my pocket.

Well, they must feel sorry as my wallet was empty and had no money in it.

But I feel sorry too as I lost some valuable cards and papers :-(
