Michigan surgeon threatened to BLOW UP operating room with a 'bomb belt' in rage over malfunctioning carbon dioxide tank and previously told staff he'd shoot himself with a .22 when he was unhappy with their work

A Michigan surgeon has been arrested for allegedly threatening to blow up a hospital after he became frustrated with a malfunctioning CO2 tank. 

Dr. Omar Najib Marar, 37, is accused of telling staff he was going to 'get his bomb belt and blow everyone up' while in an operating room at Ascension St. Mary's Hospital on January 8. 

The Saginaw Police Department arrested the colorectal specialist on February 27 and charged him with one count of false report of threat of terrorism - for which he can be sentenced to 20 years in prison. 

During his arraignment at the Saginaw County District Court, prosecutors claimed the incident was not isolated. 

In December 2022, Marar went on a tirade while performing surgery, according to Saginaw County Assistant Prosecutor Melissa J. Hoover.

Dr. Omar Najib Marar, 37, was arrested after he threatened to 'get his bomb belt and blow everyone up' 

The outburst happened in an operating room at Ascension St. Mary's Hospital on January 8

He said he was going to kill himself due to the 'staff not performing to his standards', court documents claim. 

Marar specifically stated that he would use a .22 or .25 caliber gun to shoot himself and others in the operating room while he continued to perform surgery, Hoover wrote. 

When staff reported the colorectal specialist's behavior to seniors, he allegedly warned that he would 'take out' those who turned him in. 

Court documents state that many of the staff members were terrified that Marar would go through with his threats. 

His bond was set at $100,000 cash-surety, which he posted and freed himself. He has pleaded not guilty in court.

As a condition of his bond, he is not allowed to have contact with three alleged victims. The identity of these victims has not been released by officials. 

Marar has been associated with Central Michigan University Health since 2018. 

He specializes in diseases of the colon and rectum, colon cancer, hemorrhoid surgery, Chron’s disease and ulcerative colitis. 

In December 2022, Marar said he was going to kill himself due to the 'staff not performing to his standards', according to court documents

His bond was set at $100,000 cash-surety or 10 percent, which he posted and freed himself

After his arrest, Mary Storm, a member of CMU Medical Education Partners said: 'Without commenting specifically on this case, CMU Health would like to share that the safety of our employees, patients and staff is our top priority, and we take any and all threats seriously. We also believe in a fair investigation and due process.

'However, in the event any of our staff or physicians exhibit behaviors that are deemed inappropriate or unprofessional, we take the steps we believe are necessary at the time to prevent similar actions from occurring again through coaching, mentoring, counseling, or other appropriate means based on the circumstances.'

The allegations was first looked at by the FBI but soon the investigation was taken over by the Saginaw Police Department. 

He is set to appear for a preliminary examination on March 20.
