Three teenagers have been charged with assault after a man was stabbed in Longford town on St Patrick's Day.

18-year-old Ciaran McDonnell of 34 College Park in Longford and two boys, aged 17 and 15, appeared before a special sitting of Longford District Court this morning.

The incident happened on New Street in the town on Friday night.

The court heard Mr McDonnell, when handed a copy of the charge sheet, made no reply.

Mr McDonnell was remanded in custody to appear before a sitting of Harristown District Court next Friday.

Bail was granted to the two other boys, who cannot be named due to their ages.

They were ordered by Judge Kevin Kilraine to abide by a number of conditions, including a 7pm-8am curfew, to sign-on daily at Longford Garda Station and to refrain from passing St Mel's Cathedral to enter Longford town except for legal consultations.

A man in his 30s remains in a stable condition in hospital after the incident.
