Gardaí in Galway were forced to close a nightclub in the city after a large crowd of students gathered for an unofficial Rag Week event last night.

Officers were called to the premises on Abbeygate Street at about 11pm.

There were reports of up to 1,000 people gathered on a narrow street outside.

Gardaí say a decision was made to close the venue for health and safety reasons and the crowd then dispersed.

There were no reports of any injuries.

The unofficial Rag Week is not supported by the students' union in either GMIT or NUI Galway.

Gardaí also observed Eyre Street this morning where students began queuing early for "Donegal Tuesday" celebrations.

GMIT Students' Union President Sam O'Neill encouraged any residents impacted by the event to contact the student patrol team.

Speaking on Galway Bay FM, he said some clubs and pubs were advertising drink promotions for unofficial Rag Week through social media.

He said it was not condoned by the students' union and a change in drinking culture is now evident for the majority of the student population.
