Spencer Stone, one of the American heroes who stopped a terrorist attack on a French train in August, was stabbed multiple times early Thursday in downtown Sacramento and is in stable condition, the U.S. Air Force confirmed to USA TODAY.

CBS News first reported the stabbing of the 23-year-old airman.

ABC10 in Sacramento reports that a man — apparently Stone — was brutally assaulted near 21st and K streets in downtown Sacramento around 12:45 a.m. and that police were looking for a suspect.

Stone, from Carmichael, Calif., was hospitalized in August with wounds received after he and two other Americans subdued a gunman on a Paris-bound train in August. Ayoub El-Khazzani, 25, was arrested in the attack on the French train.

“Everybody send prayers out to the Stone family today,” tweeted Alex Skarlatos, a friend of Stone who also helped stop the terror attack.

The three Americans were hailed as heroes for subduing the gunman on a Paris-bound train in Belgium. The said they acted out of instinct and were ready to fight to the death to stop the attack.

Stone, longtime friends Skarlatos, 22, an Oregon National Guardsman, and Anthony Sadler, 23, a student at Sacramento State University, were on the high-speed train from Amsterdam to Paris when El-Khazzani — armed with a Kalashnikov, an automatic Luger pistol and a box cutter — raced through the car. The men tackled and subdued the gunman, who was taken into custody in France.

“We just kind of acted, there wasn’t much thinking going on,” Stone said at a news conference in Paris days after the attack. He said  he acted out of “survival — and for my friends and everybody else on the train.”
