Police Commissioner Jamie Chalker has confirmed there will not be an investigation following a comment made by Deputy Commissioner Murray Smalpage which was accidentally shared on social media.

Deputy Smalpage apologised after accidentally posting a video on Facebook, during which he appeared to suggest 'a murder' could be a collective noun for a group of police officers.

In a statement released on Monday, Commissioner Chalker said there remained nothing "ambiguous as it relates to the actions of Deputy Commissioner Smalpage and the comments he made."

"The video and apology of Deputy Commissioner Smalpage speak for themselves and as such no investigation is required.

"I am disappointed that the comments have caused offence and apologise to those that have been impacted by them."

He also said the video was clearly published by accident.

"He clearly did not expect his comments to be broadcast to such a wide audience and this circumstance is one that serves as a timely reminder that your smartphones can be inadvertently activated as occurred on this occasion," Commissioner Chalker said.

The NT's Deputy Police Commissioner has apologised after accidentally posting a video of himself on social media suggesting 'a murder' could be a collective noun for a group of police officers.

Deputy Murray Smalpage accidentally recorded himself as he was walking around at work participating in conversations with other staff.

In one conversation, staff appear to be discussing what the appropriate collective noun is for a group of police officers.

"I think a mess of officers sounds good," a woman is heard saying.

"A murder," Deputy Smalpage suggests as he walks past.

The video was then inadvertedly posted to Facebook.

In a statement released on Sunday, NT Police said they were "aware of a video involving Deputy Commissioner Murray Smalpage that is being circulated on social media."

"The video was inadvertently recorded by Deputy Commissioner Smalpage on his phone as he was walking to a meeting and was posted to his Facebook page, and then shared by others."

Deputy Smalpage apologised, saying the comments were not "intended to be in the context that some others appear to be directing them."

"I am deeply committed to the Northern Territory police force and all its members," he said.

"Our members work incredibly hard every day to serve and protect our community.

"Again, I apologise if my remarks were construed in any other way than as part of a chat before getting down to the business at hand."
