RALEIGH (WTVD) -- A possible sexual assault is under investigation near a popular Raleigh trail.
Police say it all started Sunday morning when two people flagged down an officer on Atlantic Avenue to report a woman acting unusually.
Through the course of the investigation, authorities discovered that woman may have had an encounter with a man while walking toward the Crabtree Creek Trail.
Investigators believe, at some point, the man made sexual advances toward the woman. It's unclear where exactly that happened.
The incident remains under investigation.
