The prosecution has claimed the deception case against Catherine O’Brien showed her as a devious liar who had preyed on a vulnerable man.

Prosecution counsel Conor O’Doherty made the claim in his closing speech on Wednesday in the trial of the 47-year-old, who is accused of deception relating to the purchase, transport, and insurance of a French mare called Lingreville.
