Van Buren Police say a masked man walked into the Pointer Express Convenient Store Sunday night, pointed a gun at the clerk, and demanded money from the register.
While robbing the store, police say the man told the clerk he had a bomb and that he would set it off if she called the police.
The clerk told police the man took the money and left on foot.
A K9 unit from another agency was called to assist and track the man's scent to give investigators a general direction of which way the robber headed.
Police say they are looking for a man around 5'10" to 6' tall, and weighing between 175-200 lbs. The man was last seen wearing dark blue coveralls, a black hat with white lettering, and an olive green mask.
If anyone has any information on this crime or can identify this man, they are asked to call the Van Buren Police Department at 479-474-1234.
