POLICE in Lawless London should use hi-tech cameras to scan yobs for knives and slash crime, Sadiq Khan's Tory rival has demanded.
Shaun Bailey wants to use thermal imaging scanners to catch people concealing weapons, as he says the current stop and search policy isn't working.
He wants the Met to cough up £800,000 for American software to deploy in knife crime hotspots in Haringey, Enfield, Hackney, Waltham Forest, Southwark and Lambeth.
If he becomes London Mayor the scans would be rolled out at major events including the New Year's Eve fireworks display, Notting Hill Carnival, and the Winter Wonderland festival in Hyde Park to help stop the bloodshed on London's streets.
Crime has spiralled in the capital over the last few years, with murder rate the highest in over a decade, the latest figuresrevealed.
Mr Bailey, who wants to replace Mr Khan in the top London job in 2020, said today: "We need a new approach to stop and search because the current one is becoming less effective.
"This approach will target criminals in high traffic areas - not in a decade, not in a year, but right now.
"The current London Mayor has failed to show any real initiative in grappling with these issues."
Figures from the Mayor's Violent Crime Taskforce show that out of more than 5,000 stop and searches, just 573 arrests have been made so far.
