SAVANNAH,GA ( May 21, 2012) An 18-year-old Savannah man has been charged with a convenience store robbery and is being questioned about a second crime after a witness helped police identify him Sunday.

 Kwame Hampton who is listed as homeless was taken into custody by a Savannah-Chatham Metropolitan Police Southside Precinct officer responding to the robbery of the Parker’s Convenience Store on the 200 block of Montgomery Crossroads.

 Police were called to the store about 3 p.m. Sunday after a clerk reported a man who had entered and left the store several times had returned with a hooded shirt over his head and a weapon in his hand and robbed her of money.

 He then left, fleeing south on Atwood Drive when a bystander began following him. The bystander flagged down a responding officer and pointed the suspect out, explaining that he had taken off the jacket he wore in the robbery. A few minutes later the same bystander directed police to an apartment where he was taken into custody.

 Hampton was charged with armed robbery.

 He also has been identified as a suspect in the April 27 robbery of a man at Timberland Apartments on the 10000 block of Abercorn Street.

 In that case police were called to a fight in progress and learned that several men had beaten and robbed another man as he walked through the apartments. The man said he was lured into a stairway opening and jumped by three men.

 Police have identified Hampton as one of the men accompanying him.

 Anyone with information on either case is asked to call Crimestoppers at (912) 234-2020 or text CRIMES (274637). In the body type, include “CStop2020” plus the tip. Tipsters remain anonymous and may qualify for a cash reward.
