France Train Hero Spencer Stone Stabbed In Sacramento

Spencer Stone, one of three men who thwarted a mass shooting on a train in France, was stabbed early Thursday morning in Sacramento, California, and is in stable condition, the U.S. Air Force said.

Stone is out of surgery, according to CBS news. He was being treated for "non life-threatening but very significant injuries," said Deputy Police Chief Ken Bernard in a press conference Thursday.

The suspects, "two male Asian adults" who were wearing white T-shirts and blue jeans, fled the scene after the assault, Bernard said. It is believed they used one weapon. The investigation is ongoing.

Stone "was out with a group of friends when a physical altercation led to the victim being stabbed multiple times in his upper body," the Sacramento Police Department posted on Facebook. He allegedly has a collapsed left lung and multiple stab wounds, one source told CBS News.

The attack was not "in any way, shape or form linked to terrorism" or to the incident in France, Sacramento police said. Bernard confirmed, calling the incident "a very unfortunate altercation between two groups of folks who were enjoying the nightlife in Midtown Sacramento."

Alex Skarlatos, a childhood friend of Stone's and another of the train heroes, tweeted in response to the incident.

Stone was an Air Force medic at the 65th Air Base Group at Lajes Air Base in Portugal and is now stationed at the Travis Air Force Base in California.

Stone, Skarlatos and another childhood friend apprehended an armed gunman on a train headed to Paris from Amsterdam on Aug. 21.

France awarded all three men the Legion of Honor, the country's highest honor, following the incident. Stone was also awarded the Purple Heart and the Airman's Medal upon his return to the U.S.
