A publican and a customer were attacked by raiders armed with a meat cleaver and shotgun.
The two men were attacked as they sat in the Marsh House pub in Drogheda, Co Louth, last night.
Publican Liam Hodson sustained cuts to his face and neck and a deep gash to his hand, while patron Chris Corboy had a shotgun pointed at him.
Mr Hodson was taken to hospital for treatment but has since been discharged.
The two raiders entered a pub last night and held up staff and customers.
However, brave customers fought back and managed to hold one of the men at the scene.
The incident occurred at the pub on Marsh Street, in Drogheda, Co Louth, at approximately 8.15pm last night.
After customers tackled the raiders, the second man fled the scene.
A small amount of cash which was taken was later recovered.
Gardai subsequently arrested a 21-year-old man at the scene.
He is currently detained under Section 4 of the Criminal Justice Act at Drogheda Garda Station.
The investigation is ongoing.
