A teacher and two schoolchildren were slightly injured when pellets were fired into a schoolyard in Inchicore, west Dublin, yesterday.
Gardai are investigating the incident at the Oblates Primary School in Tyrconnell Road at lunchtime. No one was seen in the area with a gun or any other kind of weapon and the motive for the attack is unknown.
None of those injured were taken to hospital for treatment for their injuries, according to a Garda spokesman.
