The United States Navy has launched an investigation into the recent finding of a noose on a Black sailor’s bed aboard one of their warships.

According to The San Diego Union-Tribune, the unnamed Black sailor found the noose on Jan. 26. The Navy Criminal Investigative Service received an anonymous tip about the incident and began to launch a probe into the act.

“NCIS is investigating an incident aboard USS Lake Champlain (CG 57) where an object resembling a noose was found in a berthing area,” said Commander Nicole Schwegman on Wednesday (Feb. 3). “The Navy takes all allegations of Sailor misconduct and racial discrimination seriously. Due to the ongoing investigation, we will not provide further comment.”

After investigating several sailors over the weekend, they found a suspect. An unidentified crew member said that he left the noose on the Black sailor’s bed as a joke. He has been removed from the ship as the investigation continues.

As of Wednesday, the suspect has not been charged with any crime. “They’re not charged, they’re not under arrest, they’re not in custody,” an official familiar with the incident said added. “They’re just not on the ship.”

On Wednesday, the Navy task force released a report of dozens of recommendations for sailors to diminish racist and discriminatory practices. Although Chief of Naval Operations Adm. Mike Gilday applauded the swift work of investigators with the recent noose incident, he says that there is still more work that needs to be done. “… I am confident that this report’s recommendations will help make our Navy better, and we will move forward together toward meaningful, long-lasting change,” Gilday said.

This week, Defense Secretary Lloyd Austin has directed members of the Joint Chiefs to “conduct service-wide stand-downs in the next 60 days to address the problems,” according to Military.com.
