HK testing smart prisons with tracking wristbands and drug detection robotic arms

The department said the robotic arm would free officers from the unpleasant task as it automatically broke down faecal matter.

Wristbands that can keep track of inmates and robotic arms that check for drugs in poo are among new technologies to be tested at three correctional institutions under a plan to make all facilities “smart prisons”, it was revealed.

Commissioner of Correctional Services Danny Woo Ying-ming said the new technologies could help ensure safety by detecting inmates’ abnormal behaviour, including self-harming acts, more efficiently.
