Spencer Stone, one of three Americans who helped foil a terror attack on a French train in August, was stabbed in Sacramento on Wednesday night, the U.S. Air Force confirmed to NBC News.
Ston was stabbed multiple times in the torso after a fight near some popular bars in downtown Sacramento, police told NBC affiliate KCRA.
Homicide detectives were called to the scene, the station reported, adding that a man and a woman were questioned in the attack.
Stone, 25, tackled Morocco-born Ayooub El-Khazaani after the heavily armed terror suspect opened fire on a Paris train in August.
Stone was stabbed with a box cutter during the bloody struggle with El-Khazaani, and needed surgery to reattach part of his hand.
