Dorset residents have been targeted by conmen posing as police officers as part of a courier fraud scam.
Dorset Police received 19 reports of the attempted courier fraud in Weymouth last week.
Each victim reported how a man said he was calling from a police station, where they had a man in custody who had taken money from the would-be victim's bank account.
They were then told to withdraw large sums of money to send to London by courier or taxi.
The victims suspected the attempted scam and called the police. No money was stolen and Action Fraud has been notified.
