SACRAMENTO (CBS13) — Sacramento police have confirmed that France train hero Spencer Stone was stabbed early Thursday morning.

According to the Pentagon, who has confirmed Stone was injured, Spencer is in “stable condition.”

“A1C Spencer Stone has been transported to a local hospital, and is currently being treated for injury. The incident is currently under investigation by local law enforcement. He is currently in stable condition,” a statement from the U.S. Air Force reads.

Initial reports listed Stone’s condition as “critical.”

According to CBS News, who first reported the story, Stone was stabbed repeatedly. The incident happened outside of a bar at 21st and K Streets, CBS News reports. Stone reportedly suffered a wound to the heart and his left lung.

The owner of a A&P Liquors says he has video of the incident and it appears show five to six men in a group attacking someone in an intersection. Employee Ryan Romandia saw the video and says, “All you see is an altercation in the middle of the intersection…I don’t know how it started.”
