The man accused of beating a gas station clerk during a robbery in Cahokia has been arrested and is being held in a St. Louis jail.
The suspect has not been charged, so his name has not been released.
"Thanks to the public's help, and the media, we were able to capture our 33-year-old suspect who is from St. Louis," said Cahokia Police Chief James Jones.
The suspect is being held in Missouri on unrelated charges.
Cahokia police and U.S. Attorney Stephen Wigginton's office are seeking federal charges against the suspect, Jones said.
The clerk suffered bruising and other minor injuries.
The suspect is accused of robbing the BP Amoco station on Camp Jackson Road in Cahokia on Oct. 9.
"We put the information in the News-Democrat on (Oct. 10th.) And thanks to the media for their assistance, we got our suspect pretty quick," Jones said.
The suspect was arrested shortly after the robbery by the U.S. Marshals Service from the Southern District of Illinois, Jones said.
In an interview after the attack, the clerk said she feared for her life. "I could've been killed. I'm glad that I wasn't," she said.
