Sacramento police arrested James Tran on Wednesday and charged him with attempted murder for allegedly stabbing Stone outside a local nightclub in October, according to a statement by the Sacramento Police Department.
“There could be additional charges pending,” police Chief Sam Somers Jr. said at a news conference, per KCRA. “But as of right now, we’re going to classify everybody else as a witness that was involved in the altercation but Mr. Tran is being charged because he stabbed Mr. Stone.”
Stone, a U.S. Air Force Airman, gained international attention when he and two friends intervened to stop an alleged terrorist attack on a Paris-bound train in August.
The 23-year-old spoke out about the stabbing for the first time in an interview with ABC News on Thursday.
“I never thought I’d ever get stabbed in my life,” the U.S. Air Force Airman said. “The fact that it happened twice within, like, a two month period is pretty insane.”
Police are still investigating the physical altercation that left Stone seriously injured, but Somers said authorities consider Tran an instigator in the brawl, according to the Associated Press.

Somers said that Tran was arrested without incident on Wednesday and authorities discovered that the suspect both has a previous felony arrest and is affiliated with a gang, the AP reports. He said that the gang affiliation played no role in the fight.
Somers added that Tran did not know who Stone was until he saw the news reports of the stabbing. Stone echoed the statement to ABC.
“They didn’t know who I was. They were just out there maybe looking for trouble,” he said. “Looking to get in a fight or something.”
The Sacramento Bee previously showed surveillance video taken from a nearby store of the incident, showing a man in a white shirt who appears to be stone fighting with at least two other men.
In the days following the stabbing, Sacramento police asserted that the incident was not related to a terrorist act and alcohol was believed to have played a factor.
Deputy Chief Ken Bernard said then that members of Stone’s party were drinking, but it was unclear whether Stone had been drinking that night.
Stone was admitted to UC-Davis Medical Center in critical condition and was upgraded to serious after surgery, Stone’s father, Brian, previously told PEOPLE. Stone was later released an expected to make a full recovery.
