Okay kiddo, so there was a really sad and confusing situation that happened in Sheffield, England where some people did some very bad things that they shouldn't have.
There was a family with a mom, a dad, and some children. But something really bad happened where one of the adults in the family, a man, started doing something called "incest" with some of the children in the family. Incest means doing something bad with a family member, like kissing or touching in a way that is not okay.
This man did these really bad things for a long time and the children were too scared to tell anyone about it. But eventually, someone found out what was happening and they were able to get help for the children.
The man was put in trouble for what he did, which is very serious and very wrong. It's important to always tell an adult if something like this happens to you or someone you know, because it's not something that should ever happen in a family or anywhere else.
