Thames Valley Police is appealing for witnesses following two attempted robberies in Buckinghamshire, including one in Newton Longville, on Saturday 6th June.
The incidents occurred at around 12:15pm and 1:05pm at Newton Longville Post Office and the Londis on Main Street, Grendon Underwood. Nothing was stolen in either incident.
At 12:15pm, an unknown person entered the post office in Newton Longville. While inside, he produced an object suspected to be a handgun and demanded items from the cashier. The offender left the scene with no stolen property.
At 1:05pm, a person matching the description of the previous robbery attempt tried to enter the Londis on Main Street, Grendon Underwood.
The staff member in the shop became suspicious of the man and locked the doors before he was able to gain entry.
The offender is described as male, around 5ft 10ins to 6ft tall and of medium build. He was dressed in dark clothing and was wearing gloves and a V for Vendetta face mask.
He made off in a Vauxhall Astra with mud covering the front and rear index plates.
Officers responded to this second incident and following a brief pursuit, the vehicle collided with street furniture in Winslow and four people were subsequently arrested. Nobody was injured.
A 31-year-old man and a 24-year-old woman, both from Hatfield, Hertfordshire, and a 21-year-old man and a 36-year-old woman, both from Winslow had been arrested on suspicion of robbery, but they have now all been released on police bail until 4th July.
Investigating officer Detective Sergeant Dale Price, of Aylesbury CID, said: "I’m appealing for anybody who witnessed either incident on Saturday to please make contact with police."
"I’m particularly keen to hear from anyone who has dash-cam footage from the area to please check this and contact police if it has captured anything that can help this investigation."
He concluded: “You can do so by making a report online or by calling 101, quoting reference number 43200168336. Alternatively, you can contact the independent charity Crimestoppers 100% anonymously on 0800 555 111.”
