A total of three men and one woman were detained by police after the theft at a service station on the Donaghadee Road on Tuesday shortly before 11.25am.
A security guard was threatened by two men, one of whom was carrying a suspected firearm.
The pair stole a cash box, before making off in a grey coloured Renault car.
"The security guard was not injured but left badly shaken following the incident," a police spokesperson said.
A car matching the description of the getaway vehicle was recovered by police in the Ardmillan Crescent area of the town a short time later.
The arrests were made by police at different addresses in Newtownards on Tuesday.
Two men, 34 and 36 remain in custody while one man, 23, and a 20-year-old woman have been released on bail pending further enquiries.
Police are appealing for anyone who witnessed the robbery or who may have seen anyone acting suspiciously in the Donaghadee Road or Ardmillan Crescent areas to contact them.
