Eight Shamrock Rovers fans were arrested last Sunday after causing extensive damage to a Dublin pub following a fixture against rival club Bohemians.
After the match, which took place in Tallaght Stadium, Rovers' home ground, about 20 fans travelled by bus from Tallaght to the Phibsborough House pub on the northside of the city, which is close to Bohemians' home at Dalymount Park.
It is understood the Rovers fans began causing trouble in the quiet pub, smashing windows and throwing glasses.
Gardaí arrested three men at the scene and questioned a further five men at Bridewell station.
The three who were arrested were all in their late teens and were released last week. Files will be sent to the Director of Public Prosecutions.
It is understood the troublemakers have been caught on CCTV. The pub is said to have been badly damaged and is now in the process of analysing the costs and beginning repairs.
A spokesman for the Phibsborough House confirmed the incident but declined to comment any further.
A garda spokesman said: "Gardaí at Mountjoy were called to an incident in a public house in Phibsborough at 7.45pm where three men were arrested.
"Five juveniles were taken to Bridewell Garda Station and were dealt with accordingly. A large amount of damage was done to the public house.
"All three were released and a file has been sent to the DPP."
