Charges have been dropped against Zara Aleena's murderer after a prison workshop instructor pleaded guilty to having an inappropriate relationship with him.
Hayley Jones, 33, had admitted to misconduct in a public office over an inappropriate relationship with Jordan McSweeney, 31, between 6 March 2023 and 7 April 2023 at HMP Belmarsh.
McSweeney was charged with encouraging or assisting the commission of an indictable offence.
On Tuesday, during a hearing at Woolwich Crown Court, a prosecutor said the Crown Prosecution Service (CPS) had decided to drop the charge against McSweeney "in light of" Jones' guilty plea.
"Some of the evidence was that he was getting special favours or treatment," Judge David Miller said of the killer's case.
"He may have been bragging to another prisoner about the power that he had over this person."
Prosecutor Polly Dyer told the court a "full review" of the case against McSweeney had been undertaken "at the highest level of the CPS".
"The Crown's view is to offer no evidence," she said.
Ms Dyer declined to offer any more details about the decision when invited to do so by the judge.
A CPS spokesperson said after the hearing there was "insufficient evidence" to prove McSweeney's guilt.
Neither Jones or McSweeney were required to attend the hearing.
Jones, of Strood in Kent, will be sentenced on 4 February after she has been psychologically assessed.
