A MAN IN his 30s was killed after a disagreement over the movement of a chess piece, gardaí believe.

A 34-year-old man is being held in Blanchardstown in connection with the killing, which occured at around 2am this morning.

Garda sources say that the pair were playing chess when one of the men attempted to move his king. That led to a dispute over the movement of the piece. The victim was then bludgeoned with a dumbell, before being stabbed.

It is believed that the man then called gardaí himself and waited to be arrested, before giving a statement to gardaí.

A full examination of the scene is underway and the Office of the State Pathologist has been informed.

The man arrested is currently being held at Blanchardstown Garda Station under Section 4 of the Criminal Justice Act.
