Police in the north investigating a video posted online relating to Michaela McAreavey interviewed a 21-year-old man today.
The daughter of former Tyrone Gaelic football coach Mickey Harte was killed during her honeymoon in Mauritius 11 years ago.
A video was widely shared in June, showing a group of men mocking the murder of Michaela.
The PSNI says so far four men have now attended voluntarily for interview in relation to the investigation, and one 31-year-old man arrested on the 10th of August was released on bail pending further enquiries.
