The Paris gunman Karim Cheurfi was a loner with few interests in life, his former lawyer has said.
Jean-Laurent Panier described Cheurfi as an "extremely isolated" individual who passed near unnoticed while in detention in comments to BFM-TV.
Despite reports that the gunman may have been inspired by radical Islamist terrorists, Mr Panier said his client never discussed religion.
"His only conversations were about how to fill his daily life with video games," he said.
Prosecutors describe French national with a long history of violence and criminal offences but few obvious signs of radicalisation.
