Minor behaviour investigation: insight into your child's safety

If you're worried about your minor child's behaviour, friends or safety, Santos Recherchebureau offers a discreet behavioural investigation. We carefully map your child's social behaviour and immediate environment so you can act with clarity, without needlessly damaging your child's trust.

Your child talks less and less, the friend group has suddenly changed, grades are slipping. You don't want to breed distrust, but you can't look away either. We help you form a realistic picture, so you know where you stand.

Common signs

  • Sudden change in friend group or hobbies
  • A clear drop in school performance or motivation
  • Withdrawn, secretive or unusually rebellious behaviour
  • Concerns about peer pressure, substance use or unsafe contacts

How we work

Our investigations are always proportionate and centred on your child's interests:

  • Careful, non-intrusive observation of behaviour and environment
  • Mapping the social network within legal limits
  • Digital research using public sources where relevant
  • A factual report that gives you, as a parent, clarity
