ATLANTA -- A robber held up a Georgia Tech student at gunpoint early Tuesday morning, the latest in a string of armed robberies on or near the campus.

The gunman confronted the Tech graduate student about 1:00 a.m. on Luckie Street in downtown Atlanta as the victim walked to his apartment.

The robber demanded everything the student was carrying. A neighbor who saw the incident stepped out of her unit at the Centennial Street apartments and began screaming for help.

The robber got away with a pack of cigarettes.

One neighbor complained to Channel 2 Action News reporter Ryan Young that the string of robberies hasn't brought extra police patrols.

"We've had 16 stolen cars in the last two-and-a-half weeks," said the area resident who didn't want to be identified. "It's almost a no-brainer that you would want to step up security to do something about it, but that's not the case."

Another robbery victim, Jim Kenney, told WSB-TV that he was walking home Saturday night when a gunman approached him in the 1000 block of Hampton Street. The suspect told Kenney to lie on the ground, then stole his iPhone, money and sunglasses.

That robbery happened near the parking deck where Tech student Patrick Whaley was shot during a May 4 robbery.

On May 27, thieves kicked in the front door of Atlanta City Council president Lisa Borders townhome in the 300 block of Centennial Olympic Park Drive, setting off the burglar alarm.

Borders said the thieves took off empty-handed, but not before stacking her computers and food from her pantry in a neat pile in the middle of a room.
