A man with a red bandana pulled over part of his face approached the checkout counter at the Kangaroo convenience store at 4900 Brainerd Road on Monday.
"I have a gun," the man told a clerk.
The 24-year-old clerk handed over about $160 in cash before the bandit fled in an older model gray sedan with front-end damage, according to Chattanooga arrest reports.
He drove to another convenience store -- the Mapco Express at 4711 Brainerd Road -- and went to pay $10 for gas when he asked for all of the cash in the register. The clerk asked if he was serious, and he pulled the bandana over the lower half of his face. The clerk gave him $83.
Chattanooga and East Ridge police arrested Charlie Fletcher, 20, in connection with Monday's robberies in Brainerd. Police said they also suspect Fletcher committed three robberies in East Ridge.
Police tracked Fletcher down by finding his 1979 gray Buick Regal and finding it was registered to him, according to reports.
Officers went to a house at 2216 Elmendorf St. and called Fletcher and the other occupants out. He was wearing clothes like those worn by the robber.
