The trial of a cosmetic surgeon alleged to have given three women fake Botox treatment has collapsed.

Ozan Melin was formally found not guilty of three charges of fraud after he was said to have pocketed hundreds of pounds from the women by falsely stating he was medically trained.

Lisa Bolster, Melin's ex-wife and former assistant, was also cleared of fraud charges after a judge directed the jury to find her not guilty because of a lack of evidence.

And Miss Bolster, from Lytchett Matravers, Dorset, was found not guilty of a charge of unauthorised use of a trademark.

Miss Bolster, 50, had told the police that Botox vials found in her home were for personal use and Judge Brian Forster said there had been no evidence to show she was in business at the time it was seized in 2014.

But Melin, 41, will face a retrial for three offences of inflicting grievous bodily harm on Marcelle King, Jozette Shepherd and Carol Kingscott.

Judge Forster told Bournemouth Crown Court: "Sometimes difficult decisions have to be made and a judge is reluctant to become involved.

"It is not a difficult decision here, there is no evidence to support the allegation of fraud or the unauthorised use of a trademark.

"We can only look at the charge and the evidence so I direct verdicts of not guilty on those charges."

Melin, from Uxbridge, Middlesex, ran a mobile clinic called The Smooth Face Botox Company and carried out treatments at beauty salons and customers' homes.

He denies the three counts of causing grievous bodily harm.

Simon Jones, prosecuting, confirmed the Crown Prosecution Service are pursuing a retrial for the three outstanding matters.
