Two men who killed a young teacher in an attack described as "cowardly, brutal and grossly violent" have had two years added to their sentences by the Court of Criminal Appeal.

The Court of Criminal Appeal has ruled that sentences handed down to two men for killing a Co Clare schoolteacher are too lenient.

Two men have pleaded guilty to the manslaughter of a 26-year-old man in Co. Clare last Christmas.

Around 150 people have protested in Ennis, Co Clare to vent their anger over head shops.
