Famed countertenor and University of Michigan professor David Daniels and his husband, conductor Scott Walters, have been arrested on sexual assault charges. Ann Arbor police arrested the couple separately in Michigan on Tuesday and booked them into the Washtenaw County Jail, where they remained Wednesday morning, according to authorities. They’re facing extradition to Texas, where they’re accused of raping a young singer at a party nearly 10 years ago.
