Former Boston FBI Assistant Special-Agent-In-Charge Bob Fitzpatrick had no comment as he left court Thursday after he was arraigned on federal perjury and obstruction of justice charges.

The 75-year-old from Charlestown, Rhode Island, turned himself in to U.S. Marshals at federal court in South Boston in the morning.

The indictment alleges Fitzpatrick lied under oath when he was testifying for the defense in the James "Whitey" Bulger trial back in July 2013.

Steve Davis, whose sister was killed, allegedly at the hands of James “Whitey” Bulger, responds to the arraignment of former FBI agent Bob Fitzpatrick on charges of perjury and obstruction in the trial against the former mob boss.

Among the 12 counts of the indictment, the government alleges Fitzpatrick falsely claimed that Bulger told him personally that he wasn't an informant, and lied when he testified that he tried to close Bulger as an informant.

The government also alleges Fitzpatrick also perjured himself when he allegedly exaggerated his FBI career on the stand, claiming both that he personally arrested mob boss Gerry Angiulo and that he found the rifle used to assassinate Martin Luther King, Jr.

After Fitzpatrick testified in 2013, he spoke to necn outside court about the harsh cross examination from the prosecution.

"I'm not testifying for the defense or prosecution," Fitzpatrick said. "I went in there and told the truth."

Hank Brennan, one of Bulger's defense attorneys who called Fitzpatrick to the stand, took exception to the government indicting Fitzpatrick two years later.

A retired FBI agent pleaded not guilty to lying under oath while testifying in the Whitey Bulger trial in 2013.

"Was it because somehow they didn't like his story, that somehow he was adverse to the government, that he stood up to the mountain of the federal government and defied them?" questioned Brennan.
