There is a large garda presence in the area where the incident happened and a number of crime scenes have been preserved pending forensic and technical examinations by members of the Garda Technical Bureau.

Footpaths around St Stephens Green and Dawson Street are among the areas which have been sealed off and closed to members of the public.

As part of their investigations, gardai are seeking to obtain and view any video or CCTV footage of the incident and the events leading up to it.

Commenting on social media, local Sinn Fein councillor Daithí Doolan said what happened is "deeply troubling".
