An angry police officer in Iowa repeatedly yanked on the dreadlocks of a handcuffed Suspect who was arrested after a dangerous high-speed chase. Waterloo Officer Adam Wittmayer, who also hit 24-year-old Montavis Keller twice on the back of the head, was disciplined for his actions after the April 19 incident. "I don't condone Officer Wittmayer's conduct whatsoever," Waterloo Police Chief Daniel Trelka said. Keller was charged with four felonies, including attempting to assault a police officer, eluding police and possessing 42.5 grams of marijuana with intent to deliver. He did not have a prior criminal record. Frerichs handed the AP the video after the sheriff's office rejected an open records request for the footage, citing the charges. Posted By Persist
