Detroit police have suspended an officer and launched a criminal investigation into allegations he assaulted a woman after she spat on him and bit a security officer, according to The Detroit News.

According to Detroit Police Chief James Craig, officers had transported the woman — who was reportedly naked — to an area hospital, where she suddenly became very agitated, reportedly threatening hospital staff, spitting on various people, biting a security officer, and trying to bite a police officer.

The woman was treated for minor injuries at the hospital and had some minor contusions but was in stable condition, according to WXYZ-TV.
