Abstract: This article attempts to analyse behavioural traits of
lone-wolves who struck and killed innocents in six different attacks
in Europe in last nine months. The main objective of this study is
to develop a profiling template in order to capture commonality of
characteristics of these attackers. This study tries to understand the
homogeneity of lone-wolves in terms of their social background and
state of mind. The commonality among them can possibly be used to
build a profiling template that could help detecting vulnerable persons
who are prone to be self-radicalised or radicalised by someone
else. The result of this study provides us an understanding of their
commonality in terms of their state of mind and social characteristics.
