They've also been linked with two other similar incidents in Derbyshire.
Two men have been arrested and charged with robbery, following an incident at a service station in Matlock Green earlier this month.
Daniel Ingham, of Sherwood Road and Christopher Lewis, of no fixed abode, have also been charged with two further counts of robbery.
The other offences relate to incidents at service station's based in Dinting and Glossop.
They were both due to appear at Chesterfield Justice Centre yesterday.
