A University of Saskatchewan chemical engineering student who was accused of stealing acid has been cleared to return to classes, officials say.

The student had been banned from campus following allegations that arose in October of 2013.  The student, 26, had also been charged with theft. It was alleged he stole chemicals from an engineering lab at the university.

According to the university, police in Saskatoon have since dropped the charges. The matter was also considered by an internal board at the university which lifted the ban on the student in a decision in February.

"The Senate Hearing Board found that the student did not pose a risk to the campus community and could therefore return to his program of studies and to campus," the university said in a statement Monday.

No details about what the university learned about the case, in support of overturning the ban, were released.

Officials said the university acted last fall to ban the student based upon the information they had at the time and in the interest of student safety.

"While some concerns about the student’s return to campus have been raised, they have been considered by the university," the university said. "In situations where there is a perceived risk, the safety of the campus community is our top priority. When there is no perceived risk, our priority is to protect the student's privacy."
