Remember the 3 Americans who stopped a terrorist attack on a train in France?

Spencer Stone, one of three Americans who helped foil an attack on a French train this summer, is in serious condition after being stabbed outside a bar in Sacramento in what authorities have described as a “nightlife-related incident” that is not being investigated as a terrorist act.

The Sacramento police department said officers responded to a report of a stabbing in an area of midtown Sacramento known for its nightlife at 12.46am on Thursday morning. The victim, identified later by police as Stone, was believed to be out with a group of friends when a physical altercation broke out, and led to him being stabbed multiple times in his upper body, police said in a statement.

Stone was taken to UC Davis Medical Center, where he is being treated for serious but non-life-threatening injuries, according to authorities. The medical center has released a statement on behalf of Stone’s family that describes his condition as “serious”.

“The family of Airman Spencer Stone appreciates the outpouring of love and support,” the statement also said.

Sacramento police detectives were called to the scene to assist with the investigation. Police said during a morning press conference that they are searching for two adult males who fled the scene in a dark-colored car. No arrests have yet been made.
