Indianapolis police said at least 8 people were shot and killed at a FedEx facility near the airport Thursday night and 'multiple' others have injuries.

The alleged shooter also died from a self-inflicted gunshot wound, Indianapolis Metropolitan Police Department spokesperson Genae Cook said during an early morning news conference.

At least four people were hospitalized, including one person with critical injuries. Two others were treated at the scene and released. No law enforcement officers were injured.

"We have multiple people with injuries consistent with gunshot wounds," police said during a preliminary news conference after 1 a.m. ET, according to local NPR reporter Brock E.W. Turner.

Officers responded to a report of shots fired around 11 p.m. ET and found an active shooter at the scene.

The site is near the Indianapolis International Airport, according to the reports.

Police said they believe there is no active threat to the community anymore.

U.S. Rep André Carson, D-Ind., who represents the district, tweeted his condolences early Friday.

"I am heartbroken by the mass shooting at the FedEx facility here in Indianapolis and praying for all affected by this tragedy," he wrote. "I am communicating with local authorities to get all details of the attack and my office stands ready to help everyone affected any way we can."

Interstate 70 has reopened after being closed in both directions near the scene, Indiana State Police public information officer John Perrine reported on Twitter just before 1 a.m. ET but there's no access to the Ameriplex Parkway.placeholder

Parminder Singh told Fox 59 reporter Courtney Crown that his niece called to tell him she had been shot in the shoulder by the suspect while she was in her SUV at a nearby gas station but she’s expected to be OK.

Ian Johnston said his wife works at the FedEx facility and texted him to tell him there was an active shooter at her work. "She’s since notified me that she’s OK," he said. "She said she’ll be stuck in there for a while."

"You never think it might happen, but of course it can," he told FOX 59, adding that he’s "of course" "pleased as punch" to know his wife is OK.

Jeremiah Miller told WISH he was between shifts at FedEx when he heard several shots.

"This made me stand up and actually look out the entrance door, and I saw a man with a submachine gun of some sort, an automatic rifle, and he was firing in the open," he said. "I immediately ducked down and got scared and my friend’s mother, she came in and told us to get inside the car."

The scene was declared a "mass casualty, Level 1," according to WISH-TV in Indianapolis, meaning more emergency responders could head to the scene.

The FBI field office has said it's ready to assist if needed, according to freelance reporter Ethan Biando.

Police have advised anyone concerned about the safety of someone inside the facility to go to the Hilton Garden Inn Indianapolis Airport, WISH reported.

FedEx in a statement said, Safety is our top priority, and our thoughts are with all those who are affected. We are working to gather more information and are cooperating with investigating authorities, according to WTTV-TV.
