Danny Baker’s tweet mocking the Duke and Duchess of Sussex's baby is being investigated by police.
The broadcaster was sacked by the BBC after he tweeted a photo of a chimpanzee walking hand in hand with a man and woman, with the caption, "Royal baby leaves hospital."
The post sparked fury on social media, with Baker branded racist for comparing Prince Harry and Meghan Markle’s baby to a primate.
The 61-year-old deleted the tweet and apologised but it was not enough to save his job, and now police are involved after receiving a complaint.
A Metropolitan Police spokesman told Sky News: "An allegation has been received by the Metropolitan Police Service on Thursday, 9 May in relation to a tweet published on the 8 May.
"As is routine, the allegation will be reviewed and assessed by specialist officers."
Yesterday Baker took to Twitter again, this time to issue a grovelling apology.
A day after being fired from his role on BBC Radio Five Live, Baker posted a series of messages apologising for the ‘outrage’ he had caused.
He described the controversy as ‘one of the worst days of my life’ and said he made a ‘genuine, naive and catastrophic mistake’.
He said: "The picture in context as presented was obviously shamefully racist. It was never intended so - seriously who on earth would 'go there'?
“Anyway I am now paying the price for this crass & regrettable blunder and rightly so. Probably even this final word from me will extend the mania. ('Dog whistle' anyone?) I would like to thank friends on here for their kinder words and once again - I am so, so sorry.”
In a statement announcing Baker had been fired, a BBC spokesman said: "This was a serious error of judgement and goes against the values we as a station aim to embody.
"Danny's a brilliant broadcaster but will no longer be presenting a weekly show with us."
