Can I have an interpreter for a child abuse interview?

My younger son’s doctor reported me for child abuse, apparently because my son told him I was touching him in the wrong way. This is completely not true, but the workers from the child abuse office showed up at my house and wanted to interview me. I speak Arabic as my first language and while I can mostly understand English, I did not get a lot of what they were talking about. I feel they were pressuring me to talk to them. Can I make them give me an Arabic interpreter so I know fully what they are saying about me, or maybe should I consider getting an Arabic lawyer to be with me during the interview, even though I’ve done nothing wrong?
