A protest will take place at the Brazilian Embassy here on Monday following the murder of Dublin-based nurse Priscila Leonardi.
Her body was discovered by a river bank in Alegrete in southern Brazil.
She worked in Dublin, and travelled home to collect her belongings, and planned to return to Ireland.
Brazilian media states a 30-year-old man has been arrested in connection to her death.
The Irish Independent reports Priscila's friends here are demanding answers on her disappearance and death.
