The Bureau of Alcohol, Tobacco, Firearms and Explosives says one of its agents has been shot during an operation in Indiana.
ATF spokesman Thomas Ahern says he was told initially the agent sustained non-life-threatening injuries Thursday afternoon in Gary, but later said the agent's medical condition was unclear.
The agent is assigned to the Chicago Field Division.
Ahern says one offender was shot by law enforcement during the operation.
The Lake County Prosecutor says he received a report the agent was shot in the chest and that another person involved in the shooting died. The ATF agent was reportedly conducting a controlled drug buy when a shootout occurred.
