I went to a Lionel Richie concert with my partner, my son and a female friend from his work. We were dancing quietly on the side, we were not near anyone else, when a member of e security grabbed my son by the neck dragged him up the stairs punching him then threw him down concrete stairs for no reason. We were never given a reason why and assume it can only be mistaken identity. I am disgusted with these thugs you would've thought my son was a terrorist the way they manhandled him. What should've been a fun night turned into a traumatic evening. While Lionel Richie played all his hits my son was assaulted with
esecurity hits.
