(CNN) – A US Drug Enforcement Administration special agent was killed in an Amtrak train shooting in Arizona on Monday morning and two other DEA officers were injured, police said.
A DEA special agent is in critical condition and a Tucson police officer working in the DEA task force is in stable condition in a hospital, Tucson Police Chief Chris Magnus said.
The incident happened during a routine check for illegal guns, money and drugs, Magnus said.
Several officers boarded the train and made contact with two people on the second floor of the double-decker train. While officers were holding one person, a second person pulled out a handgun and opened fire on the officers, according to Magnus.
An armed man has been pronounced dead after barricading himself in a bathroom, the chief said. A second suspect is in custody.
There were 137 passengers and 11 crew on board, Amtrak said. All were evacuated.
“No injuries were reported to the crew or passengers,” Amtrak said in a statement to CNN.
Evan Courtney said he did not see or hear what happened, but was in a lounge car when “people came running up and shouting, ‘Course on fire!’
Courtney said he then grabbed his backpack and ran away. He said he huddled with strangers in a hallway, looking out the window.
“I looked out the window and saw SWAT with assault rifles huddled behind barricades,” Courtney told CNN.
“After about 15 minutes, the police ran towards us and told us to get out of the car and run in the opposite direction, out of danger.”
Video shows police facing gunman
Video broadcast live by Virtual Railfan appears to show police on a platform in Tucson confronting a gunman.
In the video, gunshots are heard near an Amtrak train, prompting an officer and the K-9 police to respond. Upon entering the train, they are confronted by the gunman, who shoots the officer as he runs for cover. The gunfire also sent passengers to the platform running for their safety.
About 15 minutes later, other officers responded to the scene. An officer is seen taking cover behind a structure on the platform. A series of gunshots ring out and someone shouts, “Put your hands up. “
Shortly after, a second officer joined his partner behind the structure. More shots are fired and one of the officers taking cover runs down the platform.
Passengers begin to exit the train once the shooting stops. They run towards the officers who tell them where to go.
An earlier tweet from Tucson Police said it was a “very active scene” and asked people to “avoid the zone” on Toole Avenue, where the Amtrak station is located.
The train, traveling from Los Angeles to New Orleans, had arrived at the station Monday shortly before 8 a.m. local time.
The FBI is leading the investigation, according to the Tucson Police Bureau and Department.
