Eight people have been killed and seven injured in a shooting at a FedEx facility in the US city of Indianapolis, police say.
The gunman began shooting “randomly” almost immediately after exiting his car, according to police.
He apparently killed himself minutes before police arrived, officials say. They have not confirmed the identities of the victims or the gunman.
This is the latest incident in a recent uptick of mass shootings across the US.
The attack began around 23:00 local time (03:00 GMT) on Thursday in Indianapolis, Indiana – the state capital and its largest city.
In a news conference on Friday, city officials said no motive had been established yet, and noted that one may never be determined.
“We’ll never really know all the ins and outs of why this occurred, but we’ll try our best,” said police chief Randal Taylor.
Craig McCartt, the deputy chief of criminal investigations, said that the gunman began firing as soon as he arrived at the building.
“This suspect came to the facility and when he came there, he got out of his car and pretty quickly started some random shooting outside the facility,” he said.
“No confrontation or argument, he just appeared to randomly start shooting,” he added.
