Multiple people have reportedly been shot in a software company office in Wisconsin.
Three nearby schools have been put on lockdown and police have rushed to the scene of the industrial park following reports of a gunman on the loose.
Four people have been taken to hospital but their conditions have not yet been confirmed, an official said.
Office workers have described seeing people running covered in blood, before officers stormed towards the building.
One witness who was in the WTS Paradigm office when the apparent shooting happened said it is now a "stable situation", but this has not been confirmed by police.

Crime scene tape is sealing off the area as onlookers stand nearby watching what is happening. TV reporters have also been urged to stay back.
One woman, who goes by the name Nurse Kelsey, wrote on Twitter: "There’s an active shooter at my husband’s job. His coworkers are shot. He is out safe. I am f***ing terrified.
"Having to explain to your 3 year old who overheard you on the phone why Daddy was scared & why he ran away from his job & what a bad man did to people her daddy works with is disgusting. Disturbing. I shouldn’t have to do this.
"The most twisted f***ed up part of this is if I had been working today & my husband had been shot, he would have come to my unit. I cannot even fathom. I’m dry heaving enough as it is.
"My husband ran out of the conference room when the gunfire started. He saw the shooter standing in until [sic] middle of the room, everyone else was in the ground. The man running out behind my husband was shot in the shoulder & abdomen."
One woman named Melissa, whose children are at the schools on lockdown, said: "There were a lot of cop cars and sirens. I thought it was a car accident.
"I went over to McDonald’s and lady had blood on her knee. I asked if she had been shot and she said no it was from glass breaking.
"She was shaken up pretty good."
A video has captured a woman screaming near the police cordon.
And a Madison television report said three ambulances were seen picking up people and quickly leaving the area.
Another report said someone called 911 after seeing a woman run out of building with a gunshot wound.
While a reporter at the scene said a friend who works in the building said "three or four people had been shot."
He added: "He told us that someone who works in the Paradigm building opened fired, shot multiple people. It sounded like he said three or four people.
"He also said the shooter is down right down."
Another WTS Paradigm worker said: “I heard gunshots fired from a semiautomatic weapon… before I left I heard about 15 gunshots and saw one person injured outside the back door.”
