Gardaí have been called to a fight on a train in Dublin.

The train was on its way from Bray to Howth this afternoon, when there was "passenger trouble" on board.

It is understood a fight broke out over a scam which involves people aggressively selling packets of tissues.

The 12:55pm Bray to Howth DART was delayed by 20 minutes, but services are now back to normal.
