The DART from Bray to Howth was delayed by 20 minutes following "passenger trouble"
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's understood a fight broke out over a scam which involves people aggressively selling packets of tissues.
The 12:55 Bray to Howth DART was delayed by 20 minutes, but services are now back to normal.
