IOWA CITY, Iowa (AP) — A police officer testified that he arrested a journalist at an unruly Black Lives Matter protest last year in Iowa after he repeatedly shot clouds of pepper spray to disperse a crowd and she did not leave. Officer Luke Wilson said he wasn’t aware Andrea Sahouri was a Des Moines Register reporter when he responded to a chaotic scene where protesters were breaking store windows and throwing rocks and water bottles at police outside Merle Hay mall on May 31.

Wilson said he sprayed the chemical irritant to clear a commercial parking lot and that it worked in scattering the rest of the group, including Sahouri’s then-boyfriend Spenser Robnett. Wilson testified on the first day of trial for Sahouri and Robnett, who face misdemeanor charges.
