Dunwoody police have arrested one of three suspects in the armed robbery of a McDonald’s near Perimeter Mall earlier this week.

Carlin Caleb Tibbs, 19, of College Park was arrested Thursday. Police said he was the driver of a vehicle that pulled up to a drive-through window at the McDonald’s at 4540 Ashford Dunwoody Road around 4 a.m. Monday just before the robbery.

While the driver ordered, two other men ran up from a location behind the building, police said. One suspect pointed a pistol at the clerk before both men jumped through the window and took an undisclosed amount of cash.

“You could tell this was planned,” Dunwoody police Sgt. Mike Carlson told Channel 2 Action News.

There is a warrant for 19-year-old Dejuan Anthony Simmons, of Sandy Springs, who remains at large. Police said he should be considered armed and dangerous. The third suspect has not yet been identified.
