On Tuesday 1 July 2014 Paul Harvey, 43, pleaded guilty at Bournemouth Crown Court to robbery and possession of an offensive weapon and was sentenced to three years four months in prison on 22 September 2014 at the same court.
The court heard evidence that at 3pm on Sunday 27 April 2014 Harvey entered the Leigh Park convenience store wearing a hat and scarf to cover his face and demanded money from a male member of staff.
Initially the staff member believed the incident was a joke but Harvey then repeated the demand while brandishing an axe.
After the shop assistant handed him Â£1200 in cash notes Harvey left the store.
Firearms officers located and arrested Harvey less than 10 minutes later by the river near to the shop.
Detective Constable Leo Glendon, of Bournemouth and Poole CID, said: â€œIt is fortunate that there were no injuries as a result of this incident.
â€œI welcome the sentence given and hope it shows potential offenders the serious way in which criminality is viewed by the courts.â€
