Stashed syringe pricks two Melbourne kids

Two children have pricked their fingers on a syringe that police believe was deliberately planted in a suburban Melbourne supermarket.

The syringe was hidden under a rail in the deli section of the Pascoe Vale Road supermarket at Broadmeadows and reported by the mother of the second child who pricked a finger an hour after the first incident on Monday, police said.

Investigators are urging people who noticed suspicious activity near the supermarket's deli section to contact Crime Stoppers on 1800 333 000.
