My sister was at a gig yesterday, the band is popular enough to tour Europe so the gig was very busy, but they are not famous. My sister has been to a lot of their gigs and is quite friendly with them. She was chatting to one of the band members near the stage after their performance, and a man approached her and her friend from behind and groped them. The man put his hand up my sisters skirt, felt her bum and between her bum cheeks and her vagina. She told the band member what was happening who immediately jumped back on to stage to get a member of security. While he was doing this, the man still didn't stop and my sister turned and punched him hard in the face. The man was then thrown out of the club.
I have told my sister to report the man as there was cctv and it happened to her friend too so it's not just her word against his, however she is reluctant because she doesn't want to be charged with assault for punching him, so thinks she should just forget about it. Of course it's her choice and I will support her, but would she be charged for that, or would it be classed as self defence?
