Candid shoeplay on the train to work results in my shoe being stolen

Description: I am on the early train to work wearing my office clothes, ballet flats and black tights and this guy gets on the train and starts filming me from behind , he keeps moving seats i assume to get a better view. while i’m playing with my shoes , dangling and looking at my phone, after a while i pushed my shoe a bit too far away from my foot and he takes my shoe and runs down the train with it. i then have to level the train and walk with just one shoe to work !
