Three men have been arrested at Dublin Airport in relation to suspected human trafficking.

Two of the men are Aer Lingus employees, while the third appeared to be trying to illegally enter the country.

Assistant Commissioner John O'Driscoll briefed the media on the arrests this afternoon.

Gardai say over 3000 people were refused entry to Ireland last year.
