The maker of a drone that fires pepper spray bullets says it has received its first order for the machine.
South Africa-based Desert Wolf told the BBC it had secured the sale of 25 units to a mining company after showing off the tech at a trade show.
It is marketing the device as a “riot control copter” that can tackle crowds “without endangering the lives of security staff”.
