A longtime employee of the University of Massachusetts says plainclothes officers came to his office to question him after someone called police to report an “agitated Black male” on campus, reports the Associated Press. Reginald Andrade told the Daily Hampshire Gazette he was following his normal daily routine Friday, walking from his morning workout to his job in the disability office in the main administration building. He says officers questioned him without telling him why. The building was locked down for about 30 minutes. Andrade says it was a clear case of racial profiling. He says the caller knew what buzzwords to use to “push the buttons of law enforcement.” Campus Police Chief Tyrone Parham told the Massachusetts Daily Collegian student newspaper, which first reported the incident, officers “tried to be as professional” as possible.
