Charges have been dropped against the last suspect still before the courts in relation to the events surrounding the death of honeymooner Michaela McAreavey.
The news came as three PSNI detectives arrived in Mauritius to assist island police with a review of the investigation.
A judge in Mauritius ruled a hotel worker could not be held on a provisional charge of conspiracy to commit larceny for an "infinite term".
Former hotel security guard Dassen Narayanen was brought before the District Court in Mapou in Mauritius on a provisional charge for the alleged offence.
He was the last person left facing any charges in the events surrounding her death. Mr Narayanen was one of three men who had been charged in connection with the death of the 27-year-old daughter of Tyrone football boss Mickey Harte in 2011.
Her husband John discovered Michaela strangled in their hotel room in a luxury resort in January 2011 on the holiday island.
Two of the men, Sandip Moneea and Avinash Treebhoowoon, were charged with the honeymooner's murder at the former Legends Hotel but acquitted after a two-month trial.
Police on the island have launched a new probe – involving different officers – into her death following the acquittals. A PSNI spokeswoman confirmed its detectives are due to spend a week aiding the review.
Separately, Mr Narayanen had faced a provisional charge of conspiring with Mr Moneea to burgle Mrs McAreavey's hotel room.
But District Magistrate Shefali Ganoo ordered the charges be struck out and found the court could not stand over Mr Narayanen remaining on a "provisional charge for an infinite term".
Mr Narayanen welcomed the court decision and revealed the "stress he had been through for the last two years".
"I cannot sleep nor can I work and I had to postpone my wedding," he said.
