PORTLAND, Ore. (AP) — A Portland man has filed a lawsuit against city of Portland and a police officer over his claims that he was wrongfully attacked and hurt during a protest last year. KPTV reports in a press conference Tuesday, Elijah Warren said he was talking to an officer on Sept. 5 about tear gas seeping into his nearby home when another officer came up from behind and clubbed him with a baton. Warren’s lawyer, Jason Kafoury, said the attack was completely unprovoked and unwarranted. The lawsuit seeks $400,000 in damages and claims the city was negligent for not providing the officer adequate training and not disciplining him for what it calls “past misuses of force” on the job.
