Fixated Threat Assessment Centre

The Fixated Threat Assessment Centre (FTAC) is a UK police/mental health unit, whose function is to manage the risk to public figures from stalkers and individuals who are fixated on high profile public figures or prominent protected sites. It was formed in 2006 in acknowledgement that perpetrators of attacks and other unwanted incidents overwhelmingly suffered from psychosis, and could often be identified in advance of any incidents from precursor behavioural signs.
