An image of a man police want to speak to about a "friend in need" scam in Gloucester has been released by police.
A man claiming to be from "the MoD in London" phoned a man asking for money to help a friend who needed money to buy a train ticket home.
The victim, 70, met the "friend" at Gloucester Railway Station who followed him to a cashpoint and turned up at his home the next day asking for more cash.
Several hundred pounds were handed over during the incident.
Gloucestershire Police said the fraudster told the victim he got his phone number from a church secretary and that his friend had just come out of hospital.
Police believe the offender may have got the victim's details from a publication, and urged people to be careful when giving out personal details.
The man, who spoke with a Scottish accent, was 5ft 7in tall, aged 44 to 55, of stocky build with short grey hair. He had a moustache and was was wearing a blue football shirt.
