Marie Farrell has told the High Court that a Detective Garda exposed himself to her while drunk and said he found it a real turn on fitting up Ian Bailey.

The shopkeeper from Schull, Co Cork is giving evidence in the former journalist's action for damages over claims he was wrongfully arrested for the 1996 murder of French film producer Sophie Toscan du Plantier.

Marie Farrell has told the jury in 1998 a detective working on the Sophie Toscan du Plantier murder investigation followed her into the ladies toilets at the golf club where she worked.

She said Garda Maurice Walsh was fairly intoxicated and that he pushed her up against the wall, exposed himself to her and said that he found it a real turn on fitting up that long english bollocks.

The court heard this to her was an indication that he was aware she'd made false statements about Ian Bailey.

The mother of five says she was acting under garda instructions when she claimed she'd seen the former journalist near the murder scene and again when she repeatedly claimed Ian Bailey was intimidating her.
