WASHINGTON — John G. Perren, special agent in charge of counter-terrorism at the FBI’s Washington field office, has been named the interim head of the office, authorities said Wednesday.
Perren will replace Joseph Persichini Jr, the assistant director in charge of the office, who officially retires on Christmas day. Perren’s appointment becomes effective Dec. 26.
Perren, who joined the bureau in 1987, spent a half year in Iraq for the FBI in 2005 as the on-scene commander before returning home to headquarters to become section chief of the Weapons of Mass Destruction/Domestic Terrorism Operations Section.
In 2008, he became the special agent in charge of the counterterrorism division for the Washington Field Office.
He replaces Persichini, who retires under a cloud. The Office of Professional Responsibility has been investigating allegations that Persichini and two other high ranking agents in the office may have worked together and may have gotten help from an FBI lawyer on an open book exam on bureau procedures, which is a violation of bureau policy.
Nothing happened to Persichini, who had been planning to retire anyways from the bureau. The two other agents still face possible discipline, which may include a demotion and a transfer to another FBI office.
