Residents and business owners in Falkirk are being told to remain extra vigilant over a spate of "distraction thefts."
Officers have received numerous reports of persons entering offices, retail, leisure and other premises, speaking with staff and customers and using distraction techniques.
This has included asking them to look at a leaflet, newspaper or similar item.
The perpetrator or their accomplice, will thereafter steal unattended personal items such as mobile phones, purses or other property from desks, countertops or from bags/coats nearby.
A Police Scotland spokesperson said: "If you are approached by any persons using this tactic please contact police via 999 if you feel threatened or in danger in any way.
"Or alternatively on 101 or online via the Police Scotland website contact us page."
