The national Indigenous broadcaster, NITV, says it has made a formal complaint against Canberra police, following the alleged intimidation of one of its journalists on Anzac Day.

Canberra-based NITV video journalist Myles Morgan was filming a march by Indigenous and non-Indigenous people along Anzac Parade, who were calling for recognition of Indigenous people killed during the colonisation of Australia, when the incident took place.

During the march a scuffle broke out between protesters and members of ACT Policing, a branch of the Australian Federal Police.

One officer drew his taser and gestured at one of the march leaders.

Morgan filmed the moment when the crowd clashed with police officers, and was later confronted by some officers demanding he hand over a copy of his vision as evidence.

The discussion was recorded on Morgan's camera.

An unedited version of the footage can be viewed on NITV's Facebook page.

"This guy has been trying to intimidate me into giving him footage," Morgan said on the recording, to two of the officers.

"You're shaking almost uncontrollably, are you OK?" said one of the officers, who later identified himself as Sergeant Mark Steel.

"I've never seen someone's face twitch like that, that's all."

Police apology requested by NITV

A third officer, who later identifies himself as station Sergeant Adrian Craft, then joins the conversation.

Morgan again stated he would be leaving the area, and would discuss the matter with his boss - unless he was under arrest.

"Unfortunately, stupidity is not illegal," Sergeant Craft said.

"We're in an interesting, philosophical juxtaposition here."

Sergeant Craft went on to further to question Morgan's motives for filming the fight - questioning its worth for an NITV news story.

"The Australian taxpayer pays you to create fair and equitable coverage," Sergeant Craft said.

In a statement to the ABC, NITV News said: "NITV has called on the Federal Police to apologise, and we have lodged a formal complaint for further investigation".

An ACT Policing spokeswoman said a complaint about the matter had been received by the AFP's professional standards team.

"As such, it would be inappropriate to respond to your questions or provide comment," she said.
