(CNN) -- Four Rikers Island guards were suspended after they reportedly failed to stop a teenage inmate from hanging himself himself in a cell in view of a guard desk.
The 18-year-old inmate was found unresponsive after the incident on November 28, the New York City Department of Correction confirmed to CNN.
A report said that at least five corrections officers did not act for seven minutes while the inmate tried to hang himself, according to The New York Times, which cited four people who spoke to the newspaper on the condition of anonymity because they were not authorized to speak about the matter publicly.
The Department of Correction suspended three officers and one captain.
The incident was captured on video that officers are supposed to periodically monitor and some of the corrections officers watched the suicide attempt, according to the newspaper.
The inmate was hospitalized and put in a medically induced coma on Tuesday, the Times reported.
Correction Commissioner Cynthia Brann said in a statement that her department is investigating, and she referred the incident, to the city's Department of Investigation, which is conducting an independent inquiry. The DOI declined to comment.
"The claims being made here are extremely troubling and we are taking them seriously. The safety and well-being of those in our custody is our number one priority and an investigation into this incident is underway," Brann said about the Times report.
"If the outcome of the investigation warrants we will take appropriate disciplinary action up to and including termination."
Elias Husamudeen, president of the correction officers' union COBA, disputed reports that the officers did something wrong.
"The correction officers assigned to this area did their job and everyone was where they were supposed to be. When they noticed this inmate attempt to take his life, they took action," Husamudeen said in a statement.
The Department of Correction, citing privacy rules, told CNN it could not release the inmate's name.
CNN has also reached out to the Bronx District Attorney's Office for comment.
