French stud authorities have contacted Irish authorities to establish if a horse being sold in France was the subject of a forged covering certificate.

The investigation by the French authorities included reference to Catherine O’Brien from Dungarvan, Co Waterford — the Cork-born woman wanted for questioning by gardaí investigating allegations of fraud in the sale of horses in the past three to four years.
