An FBI agent has reportedly been suspended because they refused to participate in a 'perp walk' of the bureau's former director James Comey, US media reports.

The agent was suspended for insubordination after finding the planned action inappropriate, according to CBS news.

Mr. Comey was indicted in Virginia on two federal charges shortly after Donald Trump urged law enforcement to take action against his political opponents, including Comey.

The FBI leadership discussed sending agents in heavy vests to bring Comey to his court arraignment scheduled next week.

During a 'perp walk', law enforcement publicly escorts an accused individual, usually in front of media cameras, a common practice for high-profile cases in the US.

Comey’s court appearance is set for 9 October, where he will face charges of lying to Congress and obstructing a congressional proceeding.

Challenges stem from Comey’s earlier testimony regarding a leak of classified information during the FBI's investigations into election interference.

If found guilty, Comey could face up to five years in prison. This indictment comes amidst a highly charged political atmosphere, coinciding with Trump's frustration over the lack of actions against his adversaries.
