THE hospital employee who opened fire on a coworker inside their medical facility’s parking garage has been nabbed after a tense lockdown.

Terrified staff and patients at Troy Corewell Health Beaumont Hospital outside Detroit, Michigan, cowered in fear after the gunman fired shots at 7 am Thursday.

The shooter fired five shots at his coworker, who is a 25-year-old man, and struck him two times in the arm in the targeted attack, the Troy Police Department confirmed.

The hospital was placed under lockdown, and surrounding schools tightened down security as law enforcement flooded the scene.

Cops believe the suspect fled the hospital after the shooting, and they released helicopters and K9 units to assist with the urgent search.

Meanwhile, the victim was taken to the emergency room, where he’s now in stable condition, the hospital confirmed.

Investigators said they will soon release a full statement about the arrest.

News of the incident broke when an Emergency Alert was sent out warning of an active shooter, ABC affiliate WXYZ reported.

“Avoid the area and shelter in place,” read the alert.

“Out of an abundance of caution, the hospital is on lockdown,” the statement read.

“Patients with services scheduled should not come to the hospital at this time.”

Video taken at the scene showed dozens of cop cars with flashing lights surrounding the property.

Barbara, a medical assistant who works at the hospital, described her fear after driving to work and seeing the cop cars.

“I was getting into the parking lot getting ready to clock in and another coworker was screaming to get in my car there was an active shooter,” she told NBC affiliate WDIV.

“I saw police officer on the parking garage with their guns drawn walking in a line.

“It’s scary. You go to your workplace thinking you’re going to be safe.

“I’m worried about my coworkers and patients.”

LOCALS’ FEAR

Schools in the surrounding district sent a message to parents warning of the shooting.

“We want to assure you that our schools remain safe and secure,” wrote a Troy School Disctrict spokesperson.

“We have taken additional security measures, and our team is closely monitoring the situation in coordination with local authorities.”

Terrified locals reported online that staff is inside hiding while cops sweep the scene.

“Need my prayer warriors to start praying,” one person wrote on X.

“My daughter is at work. They have the facility locked down so she is safe.”

Another person wrote, “My wife called me and is safe but scared.

“If you are there take cover and be safe. God bless you.”
