REPORT: Bruce McArthur beaten in prison

It seems prison isn't going well for serial killer Bruce McArthur.

Sources tell CTV News Toronto that McArthur was taken to hospital last week after being assaulted at Millhaven Institution.

There are no details on exactly what happened or how serious the injuries were.

McArthur was given a life sentence for the brutal killings of eight men with ties to Toronto's Gay Village.

In all likelihood, he will die in prison. He's not even eligible to apply for parole until he's 91-years-old.
