Gardai say they're following a definite line of inquiry following a serious assault in Co Meath yesterday.
A young man remains in a critical condition in hospital this morning after the attack on Watergate Street in Navan at around 3am.
The 21-year-old was taken to Our Lady of Lourdes Hospital in Drogheda with serious injuries and has since been transferred to Beaumont Hospital in Dublin.
Gardaí are appealing for witnesses to come forward.
