Taylor Jr., 18, of Minden, were booked on charges of attempted armed robbery. Each was jailed this afternoon on $500,000 bond.Ridley and Smith were arrested together; Knowles was captured at a separate location in Claiborne Parish; and Taylor was arrested by Minden police, Bailey said.A fifth suspect had been arrested shortly after the June 19 incident.An apparent planned robbery at the Gibsland Bank and Trust branch in the small town of Athens was foiled when the bank manager noticed someone kept peeping around a fence outside the bank. Four people fled when a customer went outside to see what was happening, Bailey said. They fled to a waiting getaway car.One person was captured within minutes and deputies found a wolf mask and two guns nearby, Bailey said.
