A fourth person suspected of the murder of an Irish newlywed at her honeymoon hotel in Mauritius appeared in court on Wednesday.

Police have confirmed that Dassen Narayanen, a 26-year-old security officer at Legends Hotel, has been charged with conspiracy.

School teacher Michaela Harte-McAreavey was found dead January 10 in her hotel room. A post mortem concluded she died as a result of “asphyxia due to compression of the neck”. Several bruises were also found on her head.

Room attendant Avinash Treebhoowoon, 29, and Sandip Moneea, 41, a floor supervisor, have been charged with murder. Room attendant Raj Theekoy, 33, faces a conspiracy charge.

Treebhoowoon and Moneea allegedly admitted to Mauritian officers that he killed Michaela McAreavey in a panic after she caught him rummaging through her belongings at a luxury hotel.

The teacher, 28, had returned to her room to get some biscuits for afternoon tea she was due to share with her husband at a restaurant in the hotel.

The killer used an electronic key card to enter the room, police said.

Thousands of mourners attended Harte-McAreavey’s funeral on Monday at the same Catholic church in County Tyrone, Northern Ireland, where she married Gaelic footballer John McAreavey on December 30. She was buried in her wedding dress in the graveyard next to the church.
