What could possibly go wrong?

"Women in fear of an attack will be able to use a phone app to summon a drone, which could arrive within minutes armed with a powerful spotlight and thermal cameras to frighten off any potential assailant," reports the Telegraph.

Trials will take place on campus at Nottingham University at a cost of £500,000 during which the tech will be used to "protect students and staff."

The scheme will be submitted to the UK government's Innovate research program, and could eventually see helicopters being replaced by drones as a front line tool of law enforcement.

"It is a high capability drone that costs just £100 an hour but can do 80 percent of what a police helicopter can do," said Richard Gill, the founder of Drone Defence.

"It cannot do high speed pursuits but it can do the other tasks such as searching for people and ground surveillance."

Gill noted that 25 drones could do the job of one police helicopter in London for the same price, with the drones being housed at five base locations across the city.
