A man in Orlando was shot and killed last night after being questioned by an FBI agent about his connection to Boston Marathon bombing suspect Tamerlan Tsarnaev.

Ibragim Todashev was being interviewed by the FBI because he had been in contact with suspected bomber Tamerlan Tsarnaev before the Boston Marathon. He had recently traveled to Boston to meet with Tamerlan, and had also planned a trip to Chechnya.The FBI agents were interviewing Todashev in his apartment near Universal Studios.

Apparently the questioning, which began without incident, turned deadly when Todashev attacked the FBI agent. The agent then shot and killed Todashev just after midnight.

Khusn Taramiv, a friend of the suspect, tells NBC News in Orlando that the 27-year-old Ibragim Todashev knew Tsarnaev because both were MMA fighters.

“We are currently responding to a shooting incident involving an FBI special agent,” FBI Special Agent Dave Couvertier told NBC News. "“The incident occurred in Orlando, Florida. The agent encountered the suspect while conducting official duties. We do not have any further details at this time. We expect to have more information later this morning.”

Taramiv says that he and Todashev were interviewed for almost three hours last night.

"(The FBI) took me and my friend, the suspect that got killed. 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," Taramiv told NBC.



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

Updates:

12:05 PM EST: Law officials are reporting that Todashev attacked the FBI agent (who was accompanied by two Massachusetts state troopers) with a knife before being shot.

9:55 AM EST: NBC News is reporting that investigators "were also looking at whether Todashev might have had any role in a triple murder in 2011, in which three men were murdered in an apartment in Waltham, Mass." This was the same triple murder that claimed the life of a man who was described by Tamerlan as his "best friend." The grisly murder involved the throats of the victims being cut, and their bodies were being covered with marijuana. No suspects were ever arrested for the murders.
