Part of Dublin Airport was evacuated on Thursday morning following a bomb scare.
Gardai have launched an investigation after Air Traffic Control received warnings that an explosive device had been placed at Pier E.
It’s understood that a male with a Northern accent phoned officials at around 1.30am and told them that a bomb was concealed in the vicinity.
The threat sparked a major security alert and airport police carried out a sweep of the area.
However after an extensive search, the location around Pier E was deemed safe.
The matter has been referred to gardai and the Dublin Airport Authority (DAA).
A number of staff members were evacuated from the area while an extensive search was carried out.
However the worrying incident has not caused any disruption to passengers travelling through the airport today.
“This matter has been thoroughly investigated and the airport is now deemed safe. There were no passengers or members of the public in the area at the time,” a DAA spokeswoman said.
