I had been in Aberdeen visiting a friend and we went out for drinks. A man who was out alone in the bar started talking to us. We thought it was a bit weird, but we didn’t want to offend him. I went to the bar to order more drinks and he followed me for some reason. When I was waiting to be served he put his arm round my waist and his other hand up my skirt and grabbed my butt cheek so hard and shook it. Me and my friend left the bar, but he followed us, not even seeming to realise we were upset.
