A masked man held up a Kum and Go in the early morning hours Thursday.
It happened at the store in the 2900 block of South National near Battlefield Road just after 3 a.m.
The suspect pointed a gun, demanded money then ran away.
Nobody was hurt.
Police set up a perimeter but they didn’t find the suspect.
Investigators hope surveillance video will give them a clue as to the masked robber’s identity.
