In at least two offences a distraction technique was used. The incidents are believed to be linked.

Officers would like to hear from anyone who can help identify either of the people pictured.

Officers have also released the following advice to help prevent you from becoming a victim:

• Keep your handbag on you, zipped with no valuable items on display (this includes your mobile phone). Do not leave it unattended.

• When paying for goods and to always ensure you shield your PIN number.

• Keep your handbag close to your body.

• In restaurants and cafés put your bag on your lap or on the floor between your feet with your foot on the strap. Alternatively place the strap through one leg of the chair.

• Never leave your bag in adjacent seats in theatres, pubs or on public transport.

• If using restrooms, do not place your handbag close to the door or side walls, particularly if there is a gap between the walls and the ground. It could be snatched from the outside.

• Do not carry large amounts of cash with you. Withdraw only money needed at the time.

• Look for ATMs located inside buildings, supermarkets or other busy locations.

• Be mindful of distractions, thieves working in pairs may attempt to divert your attention in order to steal your handbag or its contents.

• Attach your purse to your handbag with a secure cord and keep your mobile in a zipped internal pocket or on your person.
