Since new rules kicked in on Sunday, one hundred passengers arriving into Dublin Airport have failed to present a valid PCR or antigen test.
Ninety-five had no covid test results during spot checks, while five presented false tests.
They were among 80,000 people that flew into Dublin during the first 72 hours of the new rules.
RedFM news has requested a statement from Cork Airport on whether any passengers arriving into Cork have failed to
present a valid PCR or antigen test.
Muiris O'Connor from the Department of Health told yesterday's Oireachtas Transport Committee that they've now been referred to Gardaí and could face prosecution.
"As well as any follow up by the Gardai, on the health side a person that arrives without a relevant health result is required to immediately self quarantine and take a PCR test within 36 hours of arrival.
"Failure to take that PCR test within 36 hours is a further offence in law."
