MOUNT LAUREL, N.J. (CBS) — Police say two convenience stores were robbed in the same Burlington County town only minutes apart Thursday morning.

The first robbery happened at about 1:20 a.m.

Investigators say two armed men walked into the 7-Eleven store in the 100 block of Route 73 and robbed the clerk of an unspecified amount of cash. About ten minutes later, investigators believe the same suspects robbed the 7-Eleven in the 3100 block of Marne Highway.

Store manager of the Marne Highway 7-Eleven Dawn Frisco says, “The robbers seemed to just come in and know exactly what they wanted, took what they wanted and left.”

She says the robbery has left her emotionally distraught and it will take some time to recover from the experience.

The suspects then ran out of the store and remain on the loose.

There were no reports of any injuries.

Authorities hope to get some clues from surveillance video.

Anyone with information is urged to contact the Mount Laurel Police Department.
