Nightclubbers could be subjected to mobile X-ray scanners that see through their clothes in police raids on drug-dealer havens.
The X-ray machine shows the body with blurry detail of the anatomy and anything concealed beneath clothing.
Police in Britain said the images were “very graphic” but hailed their use as a fantastic success.
Victoria Police are monitoring the device, which has been used to arrest dealers and armed thugs at London clubs.
Low radiation X-rays penetrate a quarter of a centimetre into the suspect’s skin. It can reveal drugs, knives, guns and explosives under clothing.
In about six seconds the scanner produces a 360 degree image of the body without clothing.
Suspects’ bodies show up as a light colour on a monitor while foreign objects are dark.
