Perverted Security guard harassing me and my son.

At 12:20 today i entered the Golden Acre with my 12 year old son on our way to the beach. We stopped to get a snack and one of the security guys started following me back and forth asking me who i'm looking for and what i'm doing there and what do i want to buy. I asked him what the problem is and what is his name. He refused to give his name, instead he asked the lady before me in the queue does she know me and why am i speaking to her. I don't think i looked as if i was begging for money, i was asking where the queue is and i confirmed it with the lady. So i asked him again what the problem is and he couldn't answer me, still refusing to give me his name. I complained to the shop owner and she said he has a reputation for bothering women in the area and advised me to take a picture of him since he didn't want to give his name. When i tried to get a picture of him he turned away then grabbed my by the armed and pushed me. I screamed at his that he has no right to touch and he told me to shut up and stop making a scene. Please tell me what right does he have to push me??? I spoke to another security by the name of kuthvisiso. M and he advised me that the he didn't know his name either but his radio name was charlie 4 stationed right outside the Doh!nuts Store. I don't feel safe having perverted security guards misusing their power to imitate single moms. I would like you to review the footing from the cameras in the area and provide feedback on this incident. Failing to respond i will follow through wiith a civil charge of harrassment.
