Irish police are investigating if a couple who claimed in court documents that they had seen Nikita Hand's ex-partner beat her up on the same night that she was raped by former MMA fighter Conor McGregor were not living at the property in which they said they were at the time.

Affidavits sworn by Steven Cummins and Samantha O'Reilly, who were named as witnesses in Mr McGregor's failed civil court rape appeal, are currently being investigated by officers from the Garda National Bureau of Criminal Investigation (NBCI) for suspected perjury.

The couple previously rented a house directly across the road from Ms Hand in Drimnagh on Dublin's southside.

However, it is understood one of the lines of inquiry being pursued by investigators is that Mr Cummins and Ms O'Reilly, who currently live in the Cherry Orchard area of the capital, were not actually living at the address when they claim they saw Ms Hand being assaulted by her former partner on the night of December 9, 2018.

When approached by the Irish Mail on Sunday this week and asked directly if they lived at the address at the time, and to confirm the couple's whereabouts on the night, Ms O'Reilly responded by throwing a basin of water at our reporter from the top window of her council-owned home.
