why was sam faiers dad in jail

Sam Faiers' biological father was in jail because he was physically abusive towards their mother and had issues with alcohol and drug abuse. He once strangled their mother and beat her so badly she had to go to the hospital. Due to this, Sam and her sister Billie do not have a relationship with their biological father and consider their stepfather, Dave Chatwood, as their real dad. Additionally, Sam has spoken about the trauma of her stepfather going to prison for a long sentence, which affected her deeply as a child. There is also mention of her stepfather being involved in a £1 million heist and being sentenced for it. Thus, the jail time linked to the family is related primarily to her stepfather's criminal activity, while the biological father was noted for domestic violence and substance abuse issues.
