Guardian UK: Who was the Bastille Day truck attacker? Investigation under way to find out if French-Tunisian man who killed 84 people in Nice acted alone

The attacker, a 31-year-old Tunisian-born Frenchman who lived in Nice, was known to the police for common crimes – including violence – but not to the intelligence services, a police source said.

His substantial criminal record included domestic violence, theft, violence - including with a weapon - and using threats of violence.
