It has been established that a vehicle, which was being pursued by Gardaí at a distance, collided with a car on the opposite side of the road in Ballagh - a townland near Monasterevin.
Prior to the collision, social media users were commenting on local activity, with one member of the public tweeting: "Nearly wiped out this morning, car chase around Monasterevin."
"Too close for comfort. Squad cars, ambulances and even a helicopter," it finished.
It is understood passengers from both vehicles have been transferred to Tallaght hospital where one young man is said to be in a serious condition.
Gardaí have closed off the road and launched an investigation into the incident.
Our thoughts are with all those effected by the today's tragic events.
