Child's Father caused GIANT scene. HELP

So today I took my son to see his father at the mall and he caused a giant scene and I'm worried about what's going to happen. In short, I was holding our son and he began yelling profanities in my face in front of other people and their children, so they called security. Security came up to us and explain that we needed to keep it down and that couples fight but we needed to be more quiet. So after security left he kicked our sons diaper bag and left. Security return because I saw him on the camera kit the diaper bag and I explain to them that he was being aggressive and that I need wanted someone to escort me out to my car. I explain to them that I was very sorry that it happened and that I was making sure I wasn't in any trouble. The security guard explain to me that on the camera he was the aggressor and not me and that I wouldn't be in any trouble. They asked me if I lived with him or Greg came here with him and I told him no I drove myself and that we don't see each other often at all. They didn't take any names of me or him, but I'm worried if child protective services will be called. The security guard constantly reassured me that I wasn't in any trouble but I'm worried. I blocked his number right after this but what should I do now? I have no intentions of seeing him again, ever.
