same thing happened to me a 2 months ago...only, he is alone & grabbed me from the back...he did only reached my shoulders not my chest coz at the moment he's almost near me i looked back before he can grab my chest...then hit him with my bag...he's not qatari (he's wearing pants & shirt) at that moment i screamed & he run away & i'm very near to my office...our PRO was there & i told him...then he & i went back to the place but he's not there anymore...

well...my dear next time let's be more careful coz there are a lot of sick people out there...
