Two men have been jailed after committing nine robberies over 15 days in January 2019 across Hampshire, Dorset and Berkshire.
James Frampton, who's 30 and from Byron Road in Eastleigh, and Michael Purkiss who's 55 and from Arthur Road in Eastleigh, were both sentenced to 12 years.
The sentencing at Southampton Crown Court on Wednesday 12th June follows an investigation into the knife point robberies in bookmakers across three counties.
Premises were targeted between January 13th and January 27th this year.
According to police, in each case Frampton entered the betting shops with his face covered and armed with a knife.
He would demand money from the staff, threatening them if they did not comply.
Armed with the cash he would then jump in his ride outside, being driven by Purkiss, who drove him from place to place.
The pair stole more than £5000.
In total, Frampton threatened 14 members of staff working at shops in Southampton, Romsey, Holbury, Hedge End, Poole and Thatcham.
The car the pair used was registered to Purkiss' mother and was quickly identified and evidence from ANPR cameras was used by police to place the men in the locations of the robberies at the right time.
Cell site analysis of Purkiss' phone was also used to link him to the robberies and clothing seized from the pair matched that seen in the CCTV from the premises.
They were arrested in a vehicle on January 31st and charged with robbery.
Both men pleaded guilty to conspiracy to commit robbery.
Detective Constable Ali Humby from the Western Investigation Team said: "This was a fast-paced investigation that spanned three counties over 15 days.
"The level of violence threatened and the weapons used by Frampton to scare staff in these premises must have been terrifying.
"Even though no one was physically injured, experiencing this type of crime has had huge impacts on staff working at these stores.
"I hope the sentences today serve as some closure to those staff members who were subjected to these crimes.
"I also hope this sends a message to those thinking committing this type of crime is easy to get away with - it isn't.
"We will catch you, and when we do, you will go to prison for very long time."
