The officer subsequently tested positive to the virus.
An official Garda inquiry is underway after an officer who was awaiting results of a Covid-19 test attended an event with around 15 people this morning.
The Senior Gardai attended a media briefing on the Murder of Jo Jo Dullard the 21-year-old who went missing in Moone in Co Kildare, 25 years ago.
There were around 15 people present at the briefing including Jo Jo’s sister Kathleen Bergin.
Shortly after the briefing ended, the officer in attendance received a positive Covid test result.
In a statement Gardai say measures were put in place at the briefing in relation to social distancing. Members of the media were advised to only attend if essential and they were also advised they must wear a face covering.
The people present at the briefing are now restricting their movement and an internal inquiry has now been launched.
