Spokane police arrested a man who allegedly attacked a police officer while the officer was attempting to interview a possible domestic violence suspect Sunday. Officers arrested Ryan Robinson, 24, after multiple attempts to stop him from interfering with an interview failed. According to court documents, police responded to an apartment at 909 W. 9th St. for a possible stabbing and domestic violence call and encountered Robinson and “numerous uncooperative people” inside. Robinson was allegedly arguing with officers and repeatedly placing his hands in his pockets. Officers handcuffed him, but he continued arguing and used a racial epithet to refer to the officers. When police tried to interview a possible domestic violence suspect, Robinson refused to sit down and allegedly told the suspect to stop talking to police and stop answering questions. The suspect attempted to flee from police and began fighting with an officer. While Officer Ron Van Tassle was restraining the suspect, he said Robinson ran into his right shoulder, attempting to knock him off the suspect. Robinson was arrested for assault and obstruction.
