Sister's Call Over 'Triple Killer' Boyfriend Of Ex-EastEnders Actress

The sister of ex-EastEnders actress Sian Blake has branded her boyfriend Arthur Simpson-Kent a triple killer and demanded he is "brought back to justice" amid fears he has fled the country.

Murder squad detectives are urgently trying to find Simpson-Kent after three bodies, believed to be Miss Blake and her sons, Zachary, eight, and Amon, four, were found in the garden of the family home in Erith, Kent, earlier this week.

Today, Ms Blake's sister Ava said Simpson-Kent will have to "answer to God" for his actions as a photograph emerged of him arriving in Ghana.

The image, obtained by ITV News, shows him at Kotoka Airport in the Ghanaian capital Accra three days after he was questioned by police on December 16 about his partner's disapperance.

Speaking at Scotland Yard, Miss Blake broke down in tears as she paid tribute to her sister and revealed that she had planned to end her relationship with her boyfriend.

She said she also believed text messages sent to family members which claimed to be from Sian after the actress vanished had not been written by her.

"Unfortunately I believe Arthur was responsible for my sister and my (nephews') death," she said.

"I want him to face justice and explain why. It's my nephews more than anything.

"My brother is angry. My cousins are angry and it's because of the boys.

"They are angry about Sian, but the boys have devastated us. We have lost a generation. We can never replace them.

"I want him to be brought back to justice. He'll have to answer to the courts of this land and to God eventually.

"I don't know what is going through his mind."

Scotland Yard said they were aware of the photo but have refused to confirm reports that Simpson-Kent, 48, has fled to Africa.

"Whether or not he is in the country is one line of inquiry," a spokesman said.
