Caio Benicio, a 43-year-old Brazilian Deliveroo driver, is being hailed as a hero after successfully subduing an attacker outside Colaiste Mhuire on Parnell Square in Dublin. The attacker had already injured three children and two adults before Benicio intervened. In an audio message shared on WhatsApp, Benicio described how he witnessed the attack while on his motorcycle and immediately took action. He hit the attacker with his motorcycle helmet, causing him to fall to the ground. Benicio's brave act has gone viral among the Brazilian community in Ireland.

The violent scenes in Dublin continued after the knife attack, with reports of riots and clashes between protesters and police. Vehicles were set on fire, police vehicles were damaged, and shops were looted. The unrest has prompted authorities to advise the public to avoid the North City Centre area and suspend public transportation services. Garda Commissioner Drew Harris described the disorder as being caused by a "complete lunatic faction driven by far-right ideology."

The courageous actions of Caio Benicio highlight the bravery and selflessness of ordinary individuals who step up in times of crisis to protect others.
