Police were called to Interstate Blood and Plasma at 3521 Anderson Street at 1 p.m. for a report of a bullet that had been fired from a gun, according to Madison police.

According to the blood bank's regional manager Brain Kauester, the victim was an employee, and was shot in the foot while in the restroom.
