A man in his late 20s is being questioned in connection to an alleged assault in Co Longford earlier this week that left a man with serious injuries in hospital.
The man was arrested by detectives earlier this morning following an incident on Granard's Main Street at around 2am on 3 April.
The victim, also aged in his 20s, was taken to Cavan General Hospital for treatment for what have been described as "serious" injuries.
A large section of the north Longford town's main street was cordoned off for a number of hours to allow for a technical examination to be carried out.
The chief suspect, who is from the Longford area, was brought to Granard garda station for questioning under Section 4 of the Criminal Justice Act and can be held for a period of 24 hours.
It is understood the man is known to gardaí.
"The town of Granard can do without the likes of incidents such as this as it is normally such a peaceful and quiet town," local councillor PJ Reilly said.
"What incidents like this can do is deter people from coming into the town to socialise, so to hear gardaí are making progress with their enquiries is very welcome news."
