An FBI agent was reportedly relieved of duty for refusing to conduct a "perp walk" of former bureau Director James Comey in front of news cameras following the announcement of Comey's indictment last month, according to a report.

Four people briefed on the matter confirmed the dismissal to Reuters on Friday. The agency declined to comment to Reuters, however. The outlet noted that a court summons was issued, rather than an arrest warrant, but that defendants often visit an FBI field office for booking after receiving such a summons.

Comey was charged Sept. 25 with making false statements and obstructing a congressional investigation. He has maintained he is "innocent."
