DNA profiling

It could mark the end of the traditional television sleuth drama. A new device that can identify suspects from DNA left at the scene of a crime in under an hour is set to transform the way police track down criminals.

The portable technology, which is about the same size as piece of airline carry on luggage, uses a rapid form of DNA profiling to produce a genetic fingerprint from blood, saliva and skin cells left at crime scenes.

Without leaving the scene of the crime, the device, which has been developed by forensics experts, can then check the profile against the centrally held National DNA Database to reveal the identity of the criminal responsible in under an hour.
