“I’m terrified. This is clearly a blackmail threat. I need to be at home with my family.”

A friend of Katie has told the Mirror:

“The threat is still very real. An awful email was sent and Katie is terrified for Harvey’s safety.

“The police are giving Katie ­protection. She never cancels work but what is going on is so serious she just needed to be at home.

“The whole family are terrified. Katie said she will take these people to justice – she won’t have her son targeted any more.”

Sussex Police have now said:

 “It is being investigated and enquiries are ongoing.”

When police arrived at the address in Romford a woman answered the door and don’t know what they where talking about.
