Security was reportedly upped significantly ahead of the performance at the AccorHotels Arena in the French capital. Other measures taken to secure the venue included the presence of more police and sniffer dogs. Sources revealed that the man, who claimed to be an Algerian student, used a hammer during the attack and shouted: "This is for Syria". Sources also revealed that three armed men exited the vehicle and stabbed innocent bystanders.
"It appears this Ariana is like the Pied Piper of Hamelin, leading a whole generation of young people, and indeed some very young people, to a very risky place", he said, adding that Grande is "indeed a unsafe woman".
