Officers have arrested two people after an elderly woman from Bath was conned out of thousands of pounds.
The 78-year-old victim received a call on July 20 from a man posing as a police officer.
He convinced her to attend her bank and withdraw a large quantity of money. A courier then called at her house to pick the money up.
Avon and Somerset Police were alerted to the incident and have made two arrests - a 16-year-old boy on suspicion of fraud by false representation and a 28-year-old man on suspicion of conspiracy to defraud.
