The actions of the British police following the disappearance of soap actress Sian Blake are being investigated.

The remains of the ex-Eastenders star and her sons Zachary, 8, and Amon, 4, were discovered at the family home in Erith, Kent on Jan. 5. Yet the police began their inquiries on December 16 – some 20 days earlier.

Despite visiting the house and questioning Blake’s boyfriend Arthur Simpson-Kent, 48, the officers on duty did not conduct a full search of the property or its grounds.

Simpson-Kent flew to West Africa three days later. On Dec. 19 he was photographed arriving at Kotoka International Airport in Ghana and has not been seen since.

On Tuesdsay, Blake and her two children were found buried in the rear garden. Postmortem examinations have provisionally concluded that the former actress, 43, and her children died as a result of serious head and neck injuries.

In light of this, London’s Metropolitan Police voluntarily referred the case to The Independent Police Complaints Commission (IPCC). The police response, actions and decision-making will now be closely analyzed by a team of independent specialists.

The loss of Sian and her two young boys Zachary and Amon, is a tragedy and my thoughts are with their family during this very difficult time,” the IPCC Associate Commissioner Tom Milsom says in a written statement.

The IPCC will be conducting a thorough investigation into how police responded to the concerns for their welfare and their disappearance.

Sister Says Texts Sent From Blake’s Phone Were Not Written by Her

In a further twist, Blake’s sister Ava has claimed that some text messages sent from the actress’s phone in the period between her disappearance and discovery were not actually written by her.

“The first part of the text, I believe my sister may have written that,” Ava Blake told reporters at Scotland Yard on Thursday.

“But the rest of the wording and other texts my family received, they were not my sister.”

Ava Blake added, “We don’t use text lingo. We write full sentences. Starts with a capital letter and ends with a full stop. People always teased us but we did that.”

She added, “The way she signed off was to write ‘Sian’ – her full name – and cousins had nicknames and we would use them.”

“The ones that came through were very poor grammatically, bad spelling, not my sister,” she said.

Ava Blake added that the texts also stated her sister was going away “for a few weeks” before later extending this to “a few months” – something she claims her sister would never have announced via text message.

“No way,” says Ava Blake. “We’re a big family and very, very close. She would never say that. She would never not speak to us.”
