GRADY COUNTY, Oklahoma - The Oklahoma State Bureau of Investigation has been called in to investigate the death of an inmate at the Grady County Jail. 

The inmate has been identified as 28-year-old Kyle Young of Alex. Young was booked into jail October 31 for assault and battery, and obstructing a police officer.

Jessica Brown, an OSBI spokesperson said an incident occurred around Saturday, November 2. Young and another inmate got into a physical altercation. Young died during the brief fight.

Grady County Jail administrators have not said how Young died. The Medical Examiner's Office will perform an autopsy to determine cause of death.

No one has been arrested, and the other inmate has not been identified.

This is the second death at the Grady County Jail in the last two years. Federal inmate Anthony Mollman was found dead in his jail cell in May 2012.

Investigators released video of other inmates attacking Mollman inside the jail. He died as a result of his injuries. Six federal inmates are charged with murder in that case.

No word on whether Saturday's death at the jail is connected to Mollman's homicide.
