ROCHESTER. Mich. (WWJ) - A former Oakland University student who had been banned from campus and was reported missing on Tuesday has been found.

In a Safety Alert issued Tuesday, the Oakland University Police Department said it was searching for 25-year-old Alexander Walker, who was last seen on the east side of OU's campus in Rochester on Saturday. Police said Walker suffers from mental illness and may be a threat to himself or others.

Oakland University Police Chief Mark Gordon told WWJ Tuesday evening that Walker had been found outside of a gymnasium by Bloomfield Township police in their jurisdiction. He was not sure how police discovered Walker near the gymnasium, but said authorities were taking him to a hospital to be evaluated.

"I think we can all kind of breathe a sigh of relief that he was found unharmed," Gordon told WWJ.

Walker, who is currently homeless and does not have access to any vehicles, has been banned from the campus, but police did not disclose why. Authorities believed Walker may have access to weapons and told the public he was possibly dangerous.

"First and foremost, it was his well-being to get the help to him that he needs," Gordon said. "Once that assistance has been given and we feel that he's well underway for treatment, then the ban from campus can be re-evaluated. He could possibly come back as a student; that will all be re-evaluated at a future date."
