An 18-year-old Waterbury man is charged with first-degree aggravated sexual assault and first-degree kidnapping, though details of the case are secret by court order.
All that has been made public is that the rape occurred July 9.
Rashard Crawford is in jail held on $1.75 million bond.
He was also charged Thursday in connection with a robbery July 12. He had been arrested July 1 in a domestic disturbance with his sister but he released after promising to return to court on a breach of peace charge.
Waterbury police are still trying to tie Crawford to unsolved robberies, said Deputy Chief Chris Corbett, in a statement accusing Crawford of committing the violent rape alone.
"Rashard Crawford acted alone and we are not searching for any other suspects," Corbett said.
