A man in his 80s has been arrested after another man, aged in his 60s, was shot dead in Co Mayo last night.
The shooting happened at Aghamore, Ballyhaunis, just before midnight.
The victim was pronounced dead at the scene.
The arrested man is being held at Castlebar Garda Station.
It is understood that shots were discharged after the elderly man heard activity outside his property.
Initial inquiries suggest he went outside and discharged a number of warning shots, which had fatal consequences.
