A fourth man has been charged in connection with the murder of Michaela McAreavey in Mauritius on 10 January.
Dassen Narainen, 26, has been charged with conspiring in the newlywed's murder.
He is a member of the Legends Hotel security staff where the 27-year-old Co Tyrone woman and her husband John were staying on honeymoon.
Separately, a fifth man has been arrested. The 39-year-old is also a member of security staff at the hotel.
According to police on the island the man is accused of allowing electronic hotel keys be copied for criminal purposes.
He is due in court on Friday.
Three other workers at the hotel have also been charged in connection with the killing.
Room attendant Avinash Treebhoowoon, 29, and floor supervisor Sandip Moneea, 41, have been charged with murder and room attendant Raj Theekoy, 33, with conspiracy to murder.
All four charged men were remanded in police custody and will reappear before a court in a week's time.
In Mauritius, suspects are routinely remanded in police custody three times before being remanded in jail.
A police spokesman said: 'They appeared in court once more. The case will be in court once more in seven days.
'It is normal procedure that they are in court so we have more information to check.'
On Monday around 3,000 people attended the funeral of the Irish language teacher, who was the daughter of Tyrone football manager Mickey Harte.
Mrs McAreavey is thought to have been killed as she disturbed a burglary in her hotel room.
She was buried in her wedding dress at St Malachy's Church in Ballymacilroy.
