A new bike registration scheme that allows riders to mark their cycles with UV adhesive is being offered by Fairfield police.
Officers want to put the brakes on cycle thefts in Fairfield with the special kits, provided by Bike Register.
The property marking kits contain a UV fluid that is painted onto the bike and contains microscopic dots with their own unique reference code.
Fairfield Safer Neighbourhood Team will be offering the new service to a limited number of bikes during a family fun day at Fairfield Centre on Saturday.
