Gardaí in Dublin are continuing to question two men in their 20s over a fatal shooting in Tallaght almost six months ago.

35-year-old Alan O'Neill, a father of two, was shot at Kiltalown Road in May and died in hospital a short time later.

A 21-year-old man was arrested in west Dublin yesterday and a 23-year-old was detained in the midlands.

They're still being held at Tallaght Garda Station this morning.
