In Birmingham, an FBI informant in the Klan learned of a detailed plan in which Police Chief Bull Conner had agreed to give the Klan 15 minutes after the bus arrived to beat the riders before local police would arrive. The plan was reported to the FBI headquarters, but no action was taken. The Trailways station was filled with Klansmen and reporters (including Howard K. Smith). When the Freedom Riders exited the bus, they were beaten by the mob with baseball bats, iron pipes and bicycle chains, and then, battered and bleeding, they were arrested. White Freedom Riders were particularly singled out for frenzied beatings. Two riders were hospitalized, including white Freedom Rider Jim Peck with 51 stitches in his head. Rev. Shuttlesworth in Birmingham was notified of the beatings by a fleeing reporter.
