A couple were the victims of two would-be robbers at a cashpoint in Lloyds Court on Wednesday afternoon (November 26).
At about 3.35pm they were using the machine when they were approached by a man waving a newspaper at them and speaking in a foreign language.
The couple tried to push the man away, but then a second man started waving his hands around and shouting.
The offenders tried to get between the couple and the cashpoint, but the couple managed to retrieve the bank card and cash from the machine before the offenders could get to it.
A member of the public shouted at the offenders and the duo ran off with a third man.
The offenders were of Eastern European appearance and in their late twenties or early thirties. Two of the men were around 5ft 11ins, with one of them of muscular build.
The other man was shorter, around 5ft 6ins and of a slim build.
One of the offenders had a nose piercing and another was wearing a distinctive white or beige jacket with dark coloured sleeves.
They may have been driving a silver Vauxhall Passat.
Anyone with information is asked to contact Det Con Samantha Reynolds on 101.
