The suspect named as Luca Traini who has a neo-Nazi symbol tattooed above his eyebrow has been arrested. The 28-year-old who was described by a local magistrate as "lucid and determined" is said to have exhibited "no remorse for his actions".
Police investigating him on multiple counts of attempted murder with the aggravating circumstance of "racial hatred found a copy of 'Mein Kampf' by Adolf Hitler in his room where he lives.
