Second arrest made in connection with armed robbery, beating

LAWRENCEVILLE - Gwinnett police have made a second arrest in the Sept. 29 robbery and assault at a Norcross wireless store.

Investigators have charged 22-year-old Jermario Deron Jackson of Atlanta with two counts of aggravated assault, three counts of armed robbery, one count of aggravated battery and one count of possession of a firearm during the commission of a felony in connection with the robbery at the Sky Wireless store at 6050 Singleton Road, said Gwinnett County Police Chief Charles Walters.

Jackson is incarcerated with no bond in the Gwinnett County Detention Center.

Police first arrested Marcus Monger, 22, who allegedly pistol-whipped and beat 18-year-old Irfan Maya into a coma during the robbery. Monger is being held at the DeKalb County Jail on unrelated charges, according to the county's Online Judicial System Web site on Tuesday. Maya was listed in critical but stable condition at DeKalb Medical Center on Tuesday.

Monger and Jackson reportedly held up three employees at the Sky Wireless store, a T-mobile distributor, while demanding money and cell phones, according to Officer Darren Moloney, spokesman for the Gwinnett County Police Department.
