(KMOV) -- Police say a masked man armed with a rifle robbed a south St. Louis gas station early Tuesday morning.
According to authorities, the suspect walked into the Circle K in the 1500 block of Hampton around 2:30 a.m.
Police say he demanded money from the register and was handed an undisclosed amount of cash. The suspect then fled before officers arrived on scene.
The store was closed for several hours while officers investigated the incident. Authorities hope surveillance video can help lead to an arrest.
No injuries were reported.
