For at forebygge terrorforbrydelser kan medlemsstaterne i enkelttilfælde, også på eget initiativ, under overholdelse af den nationale lovgivning, levere de i stk. 2 omhandlede personoplysninger og andre oplysninger til de andre medlemsstaters kontaktpunkter, jf. stk. 3, hvis dette er nødvendigt, fordi bestemte forhold lader formode, at den pågældende vil begå strafbare handlinger som omhandlet i artikel 1-3 i Rådets rammeafgørelse 2002/475/RIA af 13. juni 2002 om bekæmpelse af terrorisme.
For the prevention of terrorist offences, Member States may, in compliance with national law, in individual cases, even without being requested to do so, supply other Member States' national contact points, as referred to in paragraph 3, with the personal data and information specified in paragraph 2, in so far as is necessary because particular circumstances give reason to believe that the data subjects will commit criminal offences as referred to in Articles 1 to 3 of Council Framework Decision 2002/475/JHA of 13 June 2002 on combating terrorism.
