'EastEnders murder suspect was a jealous thug who used to beat me and our daughter': Ex-wife says fugitive took steroids, racked up £40,000 in debts and was part of black supremacist cult

• We want a full inquiry into failings, demand Sian Blake's family after officers didn't find bodies for three weeks allowing suspect to flee to his home country of Ghana 

Dominique Deblieux, the ex-wife of murder suspect Arthur Simpson-Kent, has told how he turned from a 'kind, quiet gentleman' into a depressed, jealous thug who was a part of a black supremacist cult. Miss Deblieux, 42, said her ex-husband (pictured left together on their wedding day)- who is suspected of murdering EastEnders actress Sian Blake (right) and their two young sons (bottom right) - would often beat her and their baby daughter (pictured inset). She said he also took steroids, was obsessed with his body image and even joined an obscure black surpremacist religious group.
