ST. LOUIS COUNTY • Three banks in the St. Louis area were robbed Wednesday, two of them within about two hours, authorities say.

A First Bank at 7256 Gravois Avenue in St. Louis was robbed about 11 a.m., police said. A man approached the teller and gave her a note implying he had a weapon and demanding money. The man left with an undisclosed amount of money. No one was injured.

About 12:30 p.m. in Webster Groves, a man robbed a Reliance Bank branch at 8083 Watson Road, authorities said. The man walked into the bank and verbally demanded money but did not show a weapon. No one was injured.

And the U.S. Bank at 4301 Lindell Boulevard in St. Louis was robbed about 3:40 p.m. by a man who handed a teller a note demanding money. The robber is described by authories as a black man, 35-40 years old, who had a medium build and a goatee. He was wearing a black baseball cap, black leather coat and light blue jeans. He left the bank with cash. No one was hurt.

Investigators believe the man who robbed the Reliance bank also robbed three other St. Louis-area banks over the past month.
