In an incident police believe related to the protests, graffiti taggers sprayed the exterior walls and front sign of a plasma donor center at Washington and University avenues.
“Destroy Bio Tech” read one of the tags outside the Aventis Bio-Services building, according to the police report.
An employee said the plasma-donor center might have been targeted because of the word “bio-services” in its name. But he added the center has nothing to do bio-technology.
