A search has begun along the border of counties Cavan and Meath for two Dublin men who went missing last month.
Eoin O'Connor and Anthony Keegan were last seen in Co Cavan on the evening of 22 April.
Gardaí suspect that their disappearance is linked to the activities of an organised criminal gang.
Over 100 gardaí along with the sub-aqua unit and dog unit have begun searching an area around Mountnugent.
The area was searched last month but gardaí have now expanded the search.
