Jonesboro police say a third Dollar General store has been robbed in northeast Arkansas and investigators are trying to determine whether the holdups are related.
The Monday evening robbery was carried out by a man who pointed a small, black handgun at a cashier and demanded money.
The Jonesboro Sun reports that a prank call was made to police about the time of the robbery saying another Dollar General was being robbed.
A separate Dollar General store was robbed twice in December and police say the description of the suspect in each of the robberies is similar.
The man in Monday's holdup got away with $513 after threatening to shoot the cashier.
