Police have not ruled out any motive behind the stabbing incident, and are urging people not to spread misinformation. Violent protests erupted in Dublin after a suspected knife attack left four people injured, including three young children. Crowds of protesters clashed with police in the city center, following an attack outside a school that left a five-year-old girl and a woman in her 30s seriously injured. Two other children, a five-year-old boy and a six-year-old girl, suffered less serious injuries. A man in his 50s was detained in relation to the incident and is also hospitalized with serious injuries. Police are following a definite line of inquiry and are not looking for any other suspects at this time. While Superintendent Liam Geraghty stated that there is no terror-related activity and that it appears to be a standalone attack, Police Chief Drew Harris mentioned that all lines of inquiry were open to determine the motive. Clashes later broke out between police and protesters in the city, with a police car and a bus set on fire, and a footwear store broken into. Irish media and witnesses reported that a man armed with a knife had carried out the attack. Prime Minister Leo Varadkar expressed shock at the incident and praised the swift response of emergency services and police. Local lawmakers expressed their concern and support for the victims and their families.
