The Tánaiste and Justice Minister has confirmed that a full review of border security at Dublin Airport is underway - saying an alleged breach is "completely unacceptable."

Three men appeared in court this afternoon after an alleged human-trafficking operation was detected at the state’s main airport.

Two of the group are Aer Lingus staff members.

This evening, the Tanaiste, Frances Fitzgerald told the Dáil that maintaining the security of our borders is an “absolute priority.”

She noted that Gardaí are treating the alleged incident as a smuggling incident rather than terrorist action.

“We need to know how this happened and why,” she said. “Therefore in light of the seriousness of the situation I will work with my colleague Minister Ross to review the procedures in place so the public can have full confidence in the security of our borders.”

Three accused

Bail has been set at €22,000 for one of the men accused of facilitating human trafficking through Dublin Airport.

Peter Kernan of Old Rectory Lodge on Church Road in Celbridge, Co Kildare was one of two Aer Lingus workers brought to court today.

Mr Kernan and his colleague 56-year-old Frederick Chan - with an address at Hazelhatch in Celbridge, Co Kildare - are accused of facilitating the trafficking of a non-national into the State on January 9th and 22nd.

Judge Cormac Dunne was told it will be alleged that Mr Kernan, along with others, organised the entry of illegal immigrants by helping them to bypass passport control at Dublin Airport.

Xing Wang, who is 28 and from China with no known address in Ireland, also appeared in court this afternoon.

He is facing three charges: having a false passport, failing to produce a passport or ID and failing to present himself to an immigration officer.

Mr Wang and Mr Chan did not apply for bail today and have been remanded in custody until Friday.

While Mr Kernan was remanded in custody for a week, with consent to bail - which was set at €22.000.
