Bugs used to fight London gangs
Gangs are hard to infiltrate, police say
Listening devices and hidden cameras are being used by police in London to help infiltrate gangs of youths. Detectives hope the hi-tech gadgets - which can be placed in cars, homes or on street corners - can help yield vital intelligence.
The technology is already deployed in Lambeth, south London, where a number of teenage gangs are based.
A police spokesman said the devices are used to gather information but any evidence is not admissible in court.
Police have admitted difficulties in breaking into tight-knit groups, which often include teenagers, and identifying key figures and activities such as drug dealing or gun violence.
Such "covert tactics" have only previously been used against organised criminal networks and terrorist organisations.
A police spokesman declined to say how the technology is used by police because details would harm "operational requirements".
The admission of the Metropolitan Police's tactics against gangs came as the force released figures showing gun crime had risen 10% in the last six months.
Deputy Assistant Commissioner Janet Williams said: "You will be aware of some of our surveillance capability.
"It is using these sort of facilities and seeing if they are acceptable and we can apply them locally."
How can we help the rising cohort of people... and stop them becoming the gang members of the future
Met Commissioner Sir Ian Blair
Dept Com Williams said police were also having problems getting witnesses to come forward, especially in cases investigated by Operation Trident, which deals with gun crime among the black community.
Criminal gangs from other countries - including Nigeria, Jamaica, Turkey, Ukraine and Brazil - have been found to be operating in London this year.
Metropolitan Police Commissioner Sir Ian Blair said more effort needed to be made to stop youngsters joining gangs.
"How can we help the rising cohort of people, they are maybe 11 or 12, and stop them becoming the gang members of the future?
"The idea that people have of gangs is of a very organised Cosa Nostra (the Mafia's nickname). You are in it for life or not. That is not what these are."
