Police believe an armed robber has struck at the same bank twice within a week.
The first raid at a Royal Bank of Scotland branch in Stockport, Greater Manchester, took place on Wednesday at about 10am.
The bank in Bramhall Lane, Davenport, was targeted again today at about 9.45am as the raider produced a handgun from a bag and demanded cash from staff.
The offender is described as white and about 6ft, police said. He was wearing a grey hooded tracksuit top and bottoms, baseball cap and wore tights over his head.
Detective Constable Jeanette Lamb, of Stockport CID, said: "The offender has struck at almost the same time of the morning, using a strikingly similar MO (method of operation) and wearing an identical outfit so obviously we believe the same person to be responsible for both robberies.
"Committing one daylight robbery is one thing but to return to the same location less than a week later and threaten staff once more at gunpoint demonstrates a level of audacity rarely seen and we are working hard to identify the person responsible."
Anyone with information should call Stockport CID on 0161 856 9740 or the independent charity, Crimestoppers, anonymously on 0800 555 111.
