Have just been back to Nha Trang after a year away and have noticed an increase in crime. My phone was stolen from the Thap Ba poolside (I've been there many times before and always thought it was relatively safe). Then a few nights later my friend was leaving the sailing club about 2am with a girlfriend when some guys on motorbikes stopped, walked up to the girl, and ripped off her necklace. Then further down the street some other guys on motorbikes did the standard bag grab (on the same girl). In another incident, my friend and I were at the beach. He went for a swim and I put his iphone in my pocket whilst I sat on the bench near the beach sidewalk. He came back and we were talking then I turned around and there was a girl standing right behind me near the pocket with the phone (like about 10cm away from me) pretending to play hide and seek with a little girl who was was obviously trained very well to parade up and down the footpath in front of us. Bottom line is I don't feel as safe in this city as I once did. So look out for the thieves and be careful with your belongings. Assume you are going to be a target...
