Drones are being used to spy on pupils during university entrance examinations in China to stop them from cheating, according to Chinese media.

Officials in Luoyang, central China, have adopted the high-tech method to monitor students while they take the notoriously difficult tests.

The silent-flying drones will hover over students during university entrance exams known as ‘gaokao’, which are taken by more than nine million teenagers every year.

The devices will use 360 degree rotations to scan testing halls and locate suspicious radio signals created by hidden earpieces used to obtain the answers to exam questions.
