Three people, including a security guard, have been injured in a stabbing incident following a row in south Dublin.

It is understood an altercation between three men, aged in their 20s and 30s, was reported at Milltown on the Luas Green Line at around 8pm.

Two of the men, and a security guard who intervened, were stabbed.

Two men were arrested at the scene.

None of the victims' injuries are believed to be life threatening but gardaí said the situation could have been a lot more serious had the security guard not intervened.

The Luas stop was closed for a time for a forensic examination.
