Dominique Tricaud was speaking to The Echo following the death in recent days of Martin Graham in Ballydehob, less than three months ahead of the trial of Mr Bailey for the murder of the French woman.
Mr Graham, who was originally from Wiltshire in England, died after a long illness and was laid to rest in Ballydehob on Wednesday.
He had appeared as a witness in Mr Bailey’s case against gardaí and the State for wrongful arrest in early 2015.
He claimed in the High Court that he had been given cannabis, cash and clothes by gardaí in return for becoming friendly with Mr Bailey with the aim of getting information linking Mr Bailey to the Frenchwoman’s murder.
Mr Graham had come to the gardaí’s attention because he was staying in a house in Skibbereen which was visited by Ian Bailey shortly after he was released after his first arrest in relation to the murder in February 1997.
Mr Bailey was arrested twice as part of the garda investigation into the 1996 murder but was never charged.
Mr Bailey has always argued his innocence and has fought his extradition to France for the trial. However, his fight to prevent a French trial was rejected in France’s Supreme Court last year.
