PETERSBURG, Va. -- Petersburg Police is asking for the public’s help to identify and locate the thieves behind seven convenience store robberies in the last week.

Investigators have released the photos of two suspects caught on surveillance camera robbing Petersburg stores at gunpoint.

In surveillance video released to CBS 6, the robbers walk into the store, brandish a handgun and demand money out of the register.

"Very dangerous," says Sgt. Greg Geist, describing the suspects wanted in the recent string of robberies.

Police believe there is a connection to some of the recent robberies which have been spread out across the City of Petersburg. Police have not released the list of locations at this time.

In the seven robberies, all the suspects have worn something to cover their face, some have hoodies as well.

"We're trying to gather all the information to see if there are more that are connected," said Geist.

Police also trying to determine if one of the suspects is a male or female.

“We're unsure at this time," said Geist. "The common thread is they are all armed and they're all coming into the business with a weapon displayed.”

One patron who frequents area convenience stores is very concerned about the recent armed-robberies.

"It's real scary, when you think about it, you got kids and stuff that come in the store with you," said Arrick Bonner.

Petersburg Police also interested in finding out about a man who may be a person of interest.

"We're just trying to find out his name, he was in one of the stores prior to a robbery and we're just trying to identify who he is," said Geist.

Police ask anyone with any information about the suspects or the robberies to contact Crime Solvers at 804-861-1212 or the Petersburg Police Non- Emergency line at 804-732-4222.
