A 23-year-old Superior Township man and an 18-year-old Ypsilanti Township man were arrested a short time after police were called to the 7-11, 2200 East Ellsworth Road, at 2:20 a.m. Wednesday.
Police say the two men walked into the store, purchased something and then left.
“They were upset with the price of it,” said Sgt. Geoff Fox of the Washtenaw County Sheriff's Office.
Police would only characterize what the men bought as "a small item."
The men then returned to the 7-11. Police said the 23-year-old went inside and brandished a handgun, demanding a pack of cigarettes. He took the pack and left.
Police responding to the robbery saw the two men walking on Ellsworth and arrested them without incident. Witnesses identified suspects, and the gun was recovered, police said.
The men are being held at the Washtenaw County Jail where they were expected to be arraigned on armed robbery charges Thursday, police said.
