The 19-year-old Algerian-born migrant living in Grenoble shouts “Allahu Akbar”. He apparently threatens in Arabic language. Despite repeated demands, he refuses to let his knives fall. ” Let go of your knife “! the police in plain clothes scream. The migrant did not comply, so the policemen had to use the gun to arrest the man. The incident occurred on the 29th of October 2019.
