The Tunisian man who plowed his truck through crowds in Nice had researched the route ahead of the attack that killed at least 84 people and injured scores of others as they were celebrating Bastille Day, according to French media reports.
Mohamed Lahouaiej Bouhlel, 31, was killed by police after ramming his truck through crowds of people who were walking along Nice’s seafront promenade after a holiday fireworks display Thursday night.
Six unidentified people have been detained in connection with the killings as of Sunday, authorities said. The Islamic State group has claimed responsibility for the attack, but it’s unclear whether Bouhlel had concrete links to the group.
CCTV footage from the days beforehand show Bouhlel driving through the area in his 19-ton truck, carefully studying the scene, Europe 1 radio reported. The footage shows Bouhlel driving slowly near Nice’s Promenade des Anglais early last week.
