Gardaí in Shannon are questioning a teenager following a fatal stabbing outside The Shannon Knights in the town centre last night.

The 23-year-old man was stabbed after an altercation took place between a number of men at the night club around 3am.

Two men were injured in the row and taken to University Hospital Limerick. One was subsequently pronounced dead in the hospital a short time later while the second man, a 22-year-old, sustained injuries not believed to be life threatening.

A 19-year-old man was arrested a short time later and detained at Shannon Garda Station under Section 4 of the Criminal Justice Act.

A post mortem will take place later today at University Hospital Limerick.
