Derbyshire Police release CCTV of armed robbery
Police have released CCTV footage of two masked men who threatened shop staff with a gun during a robbery.
The men escaped with a large amount of cash after they robbed the One Stop store, in Ilkeston, on 11 September.
Detectives said the two female workers, who were also tied up, were left terrified by their ordeal.
It is hoped by showing the footage members of the public might recognise the walk and mannerisms of the two offenders.
Det Insp Donna Sisson, from Ilkeston CID, said: "The two women at the shop were getting ready to open up for the day when they were confronted by these two robbers.
"The robbery itself happened fairly quickly, but it has had a much longer term impact on the two members of staff, who were left terrified after the ordeal.
"It will take some time for them to come to terms with it."
