Charlotte-Mecklenburg police have arrested an 18-year-old in connection with a string of armed robberies, including one case in which the suspect allegedly put a gun to a victim’s head and pulled the trigger.

Police say Tony Andre Humphrey of Charlotte was arrested Wednesday and charged with 12 felony counts and one misdemeanor, involving four robberies. Police say he also was charged in connection with an unrelated fraud case.

Police say that in the Sonic robbery, the suspect pointed a handgun at the manager’s head and pulled the trigger twice. The gun did not fire either time.

Humphrey is charged with one count of attempted first-degree murder; two counts of motor vehicle theft; two counts of robbery with a dangerous weapon; one count of attempted robbery with a dangerous weapon; three counts of conspiracy to commit robbery with a dangerous weapon; felony uttering a forged instrument; felony marijuana possession; felony cocaine possession; and misdemeanor possession of drug paraphernalia.
