BREAKING: Ammon Bundy arrested after shootout with law enforcement in Oregon. One person was reportedly killed. - @AP — Elite Daily (@EliteDaily) January 27, 2016
Authorities reportedly arrested the men after a traffic stop on Tuesday afternoon.
The encounter turned violent and shots were apparently fired, ultimately killing one person.
This individual has not yet been identified. Another person, also unidentified, was also reportedly injured in the shootout and transported to a nearby hospital.
The FBI said,
During that arrest, there were shots fired. One individual who was a subject of a federal probable cause arrest is deceased... One individual suffered non-life threatening injuries.
The armed militia these men were part of occupied a federal building at the wildlife refuge since January 2.
Their presence there was controversial from the start and generated widespread criticism in terms of both the response from law enforcement and the nature of the media's coverage of the occupation.
