Door staff at venues are being handed Smart Tag, a harmless liquid spray that contains a unique marker that can only be detected by UV light.
Offenders who threaten or attack staff or revellers can be sprayed with the liquid, making it easier to identify them later once they are arrested.
The liquid takes months to wash off clothes or skin.
