This has absolutely nothing to do with racism, it's pure misogyny, and racism is being used to divert attention from misogyny so that men can continue to be abusers.
The exact same thing happened to me when I was a pre-teen/teen, and my (white English) stepfather got away scot-free, while I had male police officer corner me alone in my bedroom without a parent or female chaperone present to tell me off, tell me I was a naughty disobedient little girl, tell me random men my mum picked up and brought home for sex were allowed to do whatever they wanted to me, and tell me if I ever phoned the police again he'd "sling me in a jail cell to teach me a lesson."
There are many MANY personal stories online of men being allowed to abuse their children and the mothers being demonised as anxious, "hysterical" or trying to engage in "parental alienation", even in cases where the father has been charged or convicted of child abuse, the mother is still told if she doesn't let him have visitation, that she'll go to prison. And those are cases where the mother is trying her hardest to protect the child from an ex-husband. Cases where the mother is defending the abusive father are even harder to prosecute as no one is supporting the child at all.
And most of these men are white. White men absolutely get an easier ride when they're accused of child abuse.
It's just a racist dog whistle to pretend this particular man escaped jail because of his race. Do you really think a middle class, educated white man in his exact position would have been locked up and had the key thrown away?
British prisons aren't exactly full of posh white men who hit their kids, are they??
It's the same as the Rotherham scandal, the majority of grooming gangs in the UK are white, they get away scot-free and the press don't say a word about it, the one time it's Asian men the press blow it up into a huge scandal (while ignoring the much bigger scandals of white grooming gangs) because they know that tabloid readers don't actually give a fuck about abused children, they're just salivating at the chance to indulge in a bit of racism.
If this was a case of a white man beating his daughter with an iron bar he most likely would never have been arrested in the first place, and there definitely wouldn't be anguished Daily Mail articles about him escaping justice.
