This is a disturbing story, but it needs to be told because it relates to public safety and public health.

Toronto Police are investigating three separate incidents of human waste being thrown at someone.

The most recent was Monday night around midnight in front of the University of Toronto campus on College Street. The first was on Friday at U of T’s Robarts Library, then on Sunday at York University’s Library.

In each incident, the waste was thrown from a bucket and the suspect fled.

Investigators believe it’s the same suspect in each incident and have released a security image with hopes the individual will be recognized.
