The first person in the UK has been convicted and jailed for domestic abuse after being sprayed with SmartWater – a forensic liquid which shows up under ultraviolet light. The technology is being trialled by police forces in the hope of keeping women safe.
The substance stays on skin for up to six weeks and on clothing for much longer and categorically links the perpetrator to the specific batch of water that was sprayed.
Over 200 women across England now have the forensic deterrent packages in their homes. The packages include a hand-held canister for spraying, a gel for door handles and gates, and an automatic trap that sprays the liquid if someone approaches the house.
