An FBI agent fatally shot a man in Orlando, Florida early this morning, apparently during questioning in regards to the Boston Marathon bombing. The FBI field office in Tampa confirmed "the agent encountered the suspect while conducting official duties" but has not officially released any other details. The Times identifies the deceased as one Ibragim Todashev, and sources tell NBC News that Todashev "was originally cooperative, but he was shot after attacking the agent."

Todashev and his friend Khusn Taramiv were reportedly being investigated because they knew deceased bombing suspect Tamerlan Tsarnaev through MMA fighting. In an interview with a local NBC affiliate, Taramiv says his friend Todashev had a premonition he would be killed:

"(The FBI) took me and my friend, (Ibragim Todashev). They were talking to us, both of us, right? And they said they need him for a little more, for a couple more hours, and I left, and they told me they’re going to bring him back. They never brought him back.

"He felt inside he was going to get shot," Taramiv said about Todashev. "I told him, 'Everything is going to be fine, don't worry about it.' He said, 'I have a really bad feeling.'"

Taramiv said he left the interview, and when he came back to the apartments, he learned that his friend was killed.

CBS reports that Todashev "was being questioned by FBI agents because he had been in contact with Tamerlan Tsarnaev prior to the bombing, had been to Boston to visit Tsarnaev and had a trip planned to Chechnya."

Todashev had also been arrested earlier this month after a Florida parking lot fight with an unidentified father and son. Todashev, who was charged with aggravated battery, told police the father "got in his face" and shoved him during a dispute for a parking space. Police found the father in the parking lot with a "considerable amount of blood," and the son had a split upper lip, head injury and several teeth knocked out, NBC reports.

One law enforcement official tells ABC News, "There was some sort of aggressive movement that led the FBI agent to believe he was under threat and he opened fire."
