A man who was arrested Saturday afternoon died early Sunday after experiencing a medical emergency in his jail cell, according to the Sweetwater County Sheriff's Office.

The name of the 28-year-old man is being withheld pending notification of family. Authorities did not detail the nature of the medical emergency.
