A 1997 phone call reveals a senior garda working on the Sophie Toscan du Plantier murder believed all they had was 'very weak circumstantial evidence' against Ian Bailey.

The jury in the former journalist's damages action for wrongful arrest over the French film producer's death has been listening to a series of phone calls taped at Bandon garda station.

On June 25th 1997, Det Sgt Liam Hogan and Chief Superintendent Sean Camon discuss preparing the book of evidence for the DPP in the du Plantier murder case.

In their recorded conversation about Ian Bailey Sgt Hogan says all they have is very weak circumstantial evidence.

He tells his superior 'unless we break Jules' it is 'a 50/50' ..'we need her broken' in what appears to be a clear reference to Mr Bailey's partner Jules Thomas.

Liam Hogan, now deceased, also talks about going back to 'fill in' statements.
