Miami Valley Hospital alerted police to a woman's report she was sexually assaulted at midday Monday in an alleyway in the area of Clover Street and Steele Avenue in Dayton.
The incident came to light when the 24-year-old woman went to the hospital to make the report, News Center 7's Sean Cudahy reported Thursday night.
A nurse at the hospital -- as all medical professionals are compelled by law to do -- called 9-1-1 because the case involved a sexual assault.
The nurse told the 9-1-1 emergency operator-dispatcher that an assault kit had been performed and that Dayton police should come and get it.
The nurse, in the 9-1-1 call, said the victim was refusing to speak with police, but told emergency room personnel she was attacked about lunchtime Monday, "around 12 or so."
