Sam and Billie's biological dad went to jail because he was physically abusive towards their mother, including an incident where he beat her so badly she had to go to the hospital. His violence was linked to alcohol and drug abuse, and he left the family when Sam was two years old. Because of this, Sam and Billie have no contact with him and consider their stepdad as their real father instead.
Separately, their stepdad, Dave Chatwood, has also been arrested and charged over a £1 million bullion heist involving conspiracy to steal and handling stolen property. This case is unrelated to their biological father's imprisonment but is another reason why their family has been in the news regarding jail.
