Portugal’s authorities have raised fresh concerns about the online radicalisation of children and young people, confirming that real cases have already been identified within the country. The warning was issued during the launch of a new national awareness campaign aimed at tackling the spread of extremist content and hate narratives on digital platforms.
The alert came from both the government and the criminal police, with the Polícia Judiciária confirming that investigations have uncovered instances where young people were drawn into radical ideologies through the internet. Officials say these cases highlight how quickly online spaces can become pathways to violent extremism, particularly for vulnerable users.
The issue was discussed at a conference titled “Prevenção da Radicalização Online de Crianças e Jovens,” held at PJ headquarters in Lisbon. Speaking at the event, PJ national director Luís Neves described radicalisation as a gradual process that reshapes the identity and beliefs of children and young people, potentially leading them toward violence. He warned that this transformation often begins subtly, through exposure to extremist narratives, misinformation, and hate speech shared online.
Authorities stressed that radicalisation no longer requires physical contact or organised groups. Social media platforms, gaming forums, and encrypted messaging apps can all serve as entry points. Young users may initially encounter extremist content through memes, videos, or comments before being drawn into more closed online communities where views are reinforced and normalised.
Officials said children and teenagers are particularly at risk because they are still developing emotionally and socially. Feelings of isolation, anger, or a desire for belonging can make them more susceptible to online manipulation. Extremist networks often exploit these vulnerabilities offering simple explanations for complex problems and portraying violence as justified or heroic.
The new awareness campaign aims to address these risks through education and early prevention. Authorities are calling on parents, teachers, and schools to play a more active role in monitoring online behaviour and encouraging open conversations about what young people are exposed to on the internet. Recognising early warning signs, such as sudden changes in language, behaviour, or online habits, is seen as critical.
The government also emphasised the importance of cooperation between law enforcement, schools, technology companies, and civil society. Officials argue that policing alone cannot solve the problem and that prevention must begin long before criminal thresholds are crossed. Digital literacy and critical thinking skills are being highlighted as essential tools to help young people question and resist extremist messaging.
Portugal has so far avoided large-scale incidents linked to violent extremism, but authorities say this should not lead to complacency. The detection of online radicalisation cases suggests the country is not immune to global trends, particularly as extremist content circulates easily across borders.
PJ officials said investigations will continue, but stressed that the priority is prevention rather than punishment. raising awareness and strengthening safeguards, authorities hope to reduce the risk of young people being drawn into dangerous online spaces.
As digital platforms continue to shape how young people interact with the world, Portuguese authorities say protecting them from radicalisation has become a matter of public safety, education, and social responsibility combined.
