Investigators have been told an offender entered the female change rooms of a soccer club on Monterey Boulevard, Frankston sometime between 3pm and 4.15pm on 25 March.

It is believed they went through a bag and took a number of items, including a black Mimco wallet, Tiffany necklace, bank cards, ID cards and a small amount of cash.

A bank card was used later that day between 4.15pm and 4.40pm at a number of locations in Frankston, including a convenience store, supermarket and petrol station.

The card is believed to have been used by a man at the Seaford Road petrol station, who had stopped to fuel up on a strawberry milk beverage.
