An Irish woman has been arrested in South Africa as part of a Garda investigation into a double murder in Co Meath over eight years ago.

The 42-year-old woman was arrested in South Africa, on foot of an international arrest warrant.

She is due to appear in court later today.

Eoin O'Connor and Anthony Keegan were murdered in April 2014.

The friends were found wrapped in plastic sheeting and buried in a shallow grave on Inchicup Island, Lough Sheelin, in Co Meath.

The men, who were not regarded as major criminals, were last seen on 22 April 2014.

They had travelled from Dublin to Co Cavan for what is understood to have been a prearranged meeting.

They did not return to Dublin prompting family members to raise the alarm.

Gardaí here have been working closely with Interpol and with South African authorities over the last number of years.
