CHARLOTTE, N.C. – There is a new crime alert around Charlotte, with convenience stores being targeted by armed robbers.

Overnight and on Friday morning, three different 7-Eleven stores were robbed at gunpoint. CMPD also says they're investigating an assault that happened in the same area.

At just after 7 a.m. Friday, police say a suspect fired shots at the door of a 7-Eleven on Mt. Holly-Huntersville Road.

The manager of a nearby restaurant tells NBC Charlotte she’s worried the rash of crime could impact business.

“People want to be safe, they're not going to come out of their house knowing someone is on the loose,” says Yennifer Flores, manager of Mr. Gus Restaurant.

“It’s just concerning to me," says one woman. "It just makes me think, should I move or should I stay around?"

“I am now thinking of moving out of the area because of the robberies and the things I am hearing,” says another woman.

The same Friday morning, officers responded to a pair of armed robberies at other 7-Eleven stores; just after midnight on Providence Road and then again around 2 a.m. on Charlotte Highway in Indian Land. Those two incidents are believed to be connected, according to the Lancaster County Sheriff's office. They released a surveillance photo of the suspect.

On Wednesday, there was yet another armed robbery. Police say the suspect targeted a 7-Eleven also on Mt Holly-Huntersville Road. Police released two surveillance photos of the suspect in that case.

“It just sounds like a bad bunch of people have moved to this area and I hope police finds them and get them out,” says one woman.

Fortunately, no one has been injured in any of the recent 7-Eleven incidents.
