At least 3 people have been injured in Phoenix, Arizona after a gunman came into an office building and starting shooting on Wednesday.

ABC News reports that authorities say they are currently searching for the shooter. At this time there have been no reports of fatalities.

The shooting occurred on Phoenix's Glendale Avenue in the 7310 block of 16th Street.

USA Today reported that two of the victims have less severe injuries while three other people have been transported to hospitals nearby.

A witness said to ABC News that she hears shots and took cover in an IT closet with other people, while another witness told ABC News that they heard between 6 to 10 shots.

"This doesn't appear to be a random type of incident," Sgt. Tommy Thompson of the Phoenix Police Department said At about 10:30 a.m. to USA Today.

Reportedly the shooter came to the office building and got into a fight then drew out his gun. A few hours later SWAT came to a house about 7 miles away from where the shooting occurred as the police said to USA Today that it was connected to the shooting.

However, the suspect was reportedly not there but officers talked to someone who was not the suspect.

"I heard the shots and that's it," said Karen Frasier, a receptionist at Stearns Lending which is in the complex, said to USA Today "I wouldn't know a gunshot if it jumped up and bit me because I'd never heard one. But some other people heard them and said that's what they were."

Workers throughout the complex locked their doors and hid from windows, after they haerd the gunshots.

"Everyone was just scared, honestly, just scared," said Navika Sood to USA Today, who also works in the building.

Rob Hayter said to USA Today that he heard five or six shots and then called 911. When he looked out his office window he saw two bodies on the ground. "It was a little tense. Everybody came and hid in the IT room," he said.

Rob Hayter, who works at Pioneer Title Agency, said he heard five or six shots before calling 911, looked out his office window and saw two bodies lying on the ground.

"It was a little tense. Everybody came and hid in the IT room," Hayter said.

"According to Larry Ruch, who operates out of a law office across the street, 50 police cars, seven to eight fire trucks and K-9 units are at the location. It appeared to him that four people were taken out on stretchers; scores of onlookers took to balconies of nearby buildings to watch the scene unfold," reported USA Today.
