ST. LOUIS • A downtown bank was robbed for the second time in two days this morning.

The suspect walked into Pulaski Bank at 9th and Olive streets around 11 a.m. and approached the teller with a demand note, police said. The note indicated a weapon but the robber didn't reveal one.

The robber was described as a black man in his 50s or 60s with a slim build. He was about 5 feet 8 inches to 6 feet tall.

The man was wearing a black knit cap, a green jacket with blue sleeves, blue jeans, gloves and tan shoes. He was last seen running southbound on 9th Street.

Police are still searching for the suspect in a robbery that took place around noon yesterday at the same bank branch.

There was no indication that the two incidents were related.
