Toronto police say they are investigating two incidents of feces being thrown at students in university libraries in recent days.
Const. Allyson Douglas-Cook says officers are investigating a link between similar incidents at the University of Toronto and York University.
She says one incident occurred at the Robarts Library at U of T on Friday afternoon, while another took place Sunday afternoon at York University's Scott Library.
Douglas-Cook says detectives are looking to determine if the same suspect is responsible for both incidents.
She says assault charges could be laid.
A spokesman for York University confirmed that an "unknown male" entered the library around 5 p.m. Sunday and "deposited a substance, suspected of containing fecal matter, on a student."
"We have reached out to the victim of the assault to offer support," Yanni Dagonas said in an email.
The school has launched its own investigation and is also working with Toronto police, Dagonas said.
U of T also said it's supporting the Toronto police probe.
"As a public university we work to make the resources of our libraries as open as possible," the university said in a statement.
"What happened was shocking and assistance was provided to those affected."
