Police are targeting London's phone snatchers with invisible DNA tagging spray as Scotland Yard fights back against the brazen thieves.
Officers hope that marking e-bikes, an increasingly popular mode of getaway for marauding robbers, will allow them to track, catch and prosecute suspects.
They are also spraying riders' clothes and skin with the invisible dye, which contains a unique DNA code only seen under UV light.
The substance, known as SelectaDNA, sticks on a target for several months allowing police to link them to a specific theft via thespecial code.
The innovative method is being introduced in various hotspots around the country including London, Cambridgeshire, Hertfordshire and Scotland.
