If you believe your child is at risk of abduction you should get legal advice or contact the Gardaí. The Irish Centre for Parentally Abducted Children (ICPAC) published an ICPAC Prevention Pack (pdf) which provides information on the steps you should take if your child is at risk of abduction. This includes advice on gathering important information relating to your child, which will be required if your child is abducted, as well as on other steps you can take to reduce the risk. Reunite International, a UK charity, also provides child abduction prevention guides on its website.
