Armed gardai intercepted a Luas after receiving a report that a youth on board had a gun.
A number of youths were removed from the Red Line in Drimnagh tonight after armed members of the force entered the tram and took them off.
Confused passengers were held on a tram this evening as gardai entered before shouting "get on the ground" at a person on board.
Around seven gardai stormed the tram and a group were removed.
After carrying out a search no gun was found.
One witness told Dublin Live the scene was "like something out of a movie" and that officers were "very wary" for the safety of others on board.
She said:"It was like something out of a movie. Just a lot of shouting to get on the ground , the gardai were very wary of us on board to blocked the doors."
A garda spokesperson confirmed the incident saying they received a report that a youth was carrying a gun.
She said "A number of youths were travelling on the Luas when it was alleged that one youth was carrying a firearm.
"Gardai stopped the Luas at approximately 7.45 p.m. and a number of youths were removed from the Luas.
"There was no firearm and investigations ongoing."
