An attacker stabbed a man multiple times in an early-morning attack in the south inner city.
The victim, who is aged in his 30s, was rushed to hospital soon after the incident, which happened near Grafton Street yesterday.
Bloodstains were visible on the path and on a street signpost in the aftermath of the attack. Officers from Pearse Street Garda Station are leading the investigation into the horrific stabbing.
It happened at around 3.45am on the Luas Green Line outside the main entrance at St Stephen's Green.
The victim was taken to St James's Hospital after sustaining injuries to his leg and arm.
However, despite the fact he was struck multiple times, his injuries were not believed to be life-threatening.
A source told the Herald the victim was slashed several times with a knife during the early-morning incident.
"He sustained minor injuries to his leg and arm and was taken to St James's Hospital," said the source.
"He was released shortly afterwards and investigations are ongoing."
Disruption was caused for commuters throughout the morning as the scene of the incident was sealed off for examination by gardai.
Luas commuters were also affected, with no trams able to pass through the Grafton Street and St Stephen's Green junction. Passengers were asked to exit trams at the Dawson stop heading southbound and at St Stephen's Green heading northbound and walk between stops.
Dublin Bus accepted Luas tickets for the duration of the disruption, a Luas spokesperson confirmed.
The line was reopened later in the morning.
"No arrests have been made and investigations are continuing," a garda spokesperson said after the attack.
