Criminal gang members used a swarm of drones to obstruct FBI agents during a hostage raid

A criminal gang used a swarm of drones to disarm and prevent law enforcement agents from carrying out a hostage rescue, an FBI official has revealed. A group of tiny drones amassed on the FBI agents outside an unidentified US city, making a series of'high-speed, low passes at agents in the observation post' in an attempt'to flush them' from their position, according to Defense One. 'We were then blind,' said Joe Mazel, head of the FBI's Operational Technology Law unit, at the AUVSI Xponential conference in Denver. 'It definitely presented some challenges'. The disconcerting incident casts a light on the growing ways that criminals, hackers and others are using drones to carry out a number of illicit activities.
