Measures have been put in place to stop a baby killer contacting her dead twins' paternal grandmother, according to their grieving dad.

Samantha Ford was sentenced to 10 years in prison after admitting two counts of manslaughter after the death of 23-month-olds Jake and Chloe on Boxing Day last year.

On Sunday, the twins’ father Steven Ford tweeted revealing the killer had sent his mother a letter from the mental health unit in which she is residing until she is deemed fit to go to prison.

He said: "The UK failed justice system strikes again. The murderer who killed my children has sent a twisted letter to my mum. Trevor Gibbens Unit in Maidstone should be ashamed for letting this happen. The injustice continues."

Speaking to KentOnline, Mr Ford said: "My mum is absolutely distraught by this. It's made her ill. She's been crying all day.

"The letter is her blaming me for the death of my children. Blaming my mum for not supporting her and she calls me a sicko and says my behaviour is disgusting.

"It's further proof she is a narcissist. She says she won't return my children's belongings to me, which her family have, and that she will not make the divorce easy.

"Not once does she say sorry for what she has done."

Mr Ford today confirmed he has had a "positive" meeting with Kent and Medway NHS and Social Care Partnership Trust (KMPT), which runs the Trevor Gibbens Unit.

He tweeted: "They've accepted the letter shouldn't have been sent and were manipulated into sending it by using only my mum's first name and lied about who she is.

"Measures have been put in place to prevent any further contact."

Speaking to KentOnline, he added: "They've accepted it was an issue that shouldn't have happened and have apologised."

A spokesman for KMPT previously said: “Nationally clear guidance is set for secure care environments, this includes guidance from the Ministry of Justice, the CQC and the Mental Health Act.

“Staff working within secure care settings ordinarily have no legal powers to interfere with postal items but may withhold outgoing post from a detained patient where it has been requested that this be done.

“If a patient has been found to send inappropriate letters containing offensive content, we will investigate thoroughly and take appropriate action.”

Mr Ford last saw his children on Christmas Day before letting them go to their mother's house in Margate.

He has since launched an appeal of the sentence she was given by the judge, but this was turned down.
