A man drove his car toward a crowd of pro-Palestinian protesters at Portland State University (PSU) and sprayed a chemical agent like pepper spray before running away, police said Thursday night.
Police had clashed with protesters, arresting at least 30 people during a sweep of the university’s library after it had been occupied for several days.
Tensions came to a head Thursday, when protesters refused to leave the campus area and overtook the campus building for the second time.
