Windsor police say Ontario's Special Investigations Unit is "monitoring" a case in which a woman was arrested Wednesday.
The information was revealed on the Windsor Police Service's Facebook page. It came in response to a post from a member of the public, who claims he witnessed the incident.
In the Facebook post, it's said the incident happened late Wednesday, in the 500 block of Aylmer Avenue.
The woman was brought to hospital for treatment, the service's post says.
Police have not given any further information about what happened or how serious the injuries are.
The posting says police "will provide further details as they become available."
A request for interview wasn't immediately returned by Windsor police.
