I heard about this really horrible situation, would should i do if i saw this happen.?

don't worry, Your not a troll, this did happen to me when I was walking home from school once,and a group of girls made me do the same sort of thing, except, they left my panties on, and i have a set of g cups. later that day, one of the boys came by my house and asked me "why were you nude in the middle of the park?" i replied, some girls made me do it. he told me that a lot of boys were sorry and wondered what happened he said. so basically, i think he felt sorry about what hapend to me.
