A man has been arrested after three people were injured in a suspected knife attack that left a Dublin neighbourhood in “a state of shock”.

The suspect was understood to be from a South American country and not an asylum seeker, Irish media reported.

Three men were injured in an apparent series of random attacks across several streets in the Stoneybatter area of the Irish capital on Sunday.

Emergency services were called to the scene around 3pm. Residents were ordered to lock their doors and stay inside.

Two men had “serious but not life-threatening” injuries, while the other man’s injuries were described as “less serious”, the Gardaí said.
