Police are looking for an assailant in Minneapolis who has been targeting bicyclists in the area by throwing cement bricks at them.
Mackenzie Jensen, 20, the most recent of at least four victims, requires facial reconstruction surgery after the suspect threw a cinder block at him from a passing vehicle Friday afternoon. The block hit Jensen in the face and knocked him off his bike, according to NBC affiliate KARE 11.
"[It] came flying at him out of nowhere and just cracked him in the face," his mother, Kristin Piper, told CBS News.
