Gardaí investigating the murders of Eoin O'Connor and Anthony Keegan in Meath have arrested a man.

The bodies of the men in their 30s were discovered on an island in Lough Sheelin, County Meath in May, a month after they were reported missing.

The man in his 50s is being detained under the Offences Against the State Act 1939 at Kells Garda Station.

This is the third arrest to date in relation to this investigation.

In June, gardaí arrested two men in the Cavan area.
