The officer was killed after receiving gunshot wounds during an incident in Castlerea shortly before midnight.
Gardai have confirmed the officer killed in the shooting was detective Colm Horkan from Charlestown, Co Mayo.
One man, in his 40s, has been arrested in connection with this investigation and is currently detained in Castlerea Garda Station.
A spokesman said: "It is with deepest sadness An Garda Síochána confirms the death of our colleague, resulting from fatal gunshot wounds received during an incident in Castlerea shortly before midnight on Wednesday 17th June 2020."
Gardai in Castlerea have launched a murder investigation.
